I'll just start you off. Please feel free to get creative with Mattrick ahead of the event.
Tonight's the night. We've waited years for this, the final piece of the next-gen puzzle. Tonight we'll see what the next Xbox is all about.
Microsoft steps into the ring at 6pm UK time, and you can watch the entire show live here. An embedded video of the live stream will appear below then.
The Eurogamer team will be right here with you, reacting with real-time commentary to everything that goes down. Your thoughts will run alongside our own, the most eye-catching of them being dragged into the main report for everyone to see.
Meanwhile Tom Bramwell, our man at the show in Redmond, will watch and absorb, priming his question-cannon for the interviews ahead.
So, what will happen? We've talked about everything known so far, and that's quite a lot, but there are still plenty of questions that need answering. What will Xbox boss Don Mattrick be wearing? Will Usher be there? Will Steve Ballmer be sweating somewhere in the audience and maybe even on stage?
Be warned that Microsoft may keep plenty in reserve for E3 next month, although the Xbox maker will also be keen to put one over on Sony and its PS4 reveal. Who will triumph? Who cares? It'll be fun to watch.
Any EG Staff reading this? Will you host video of the event afterwards. I don't get home until 8 and want to know where I can watch it?
Yep, the live video stream on this page will be replaced with an on-demand video about an hour after the conference ends - which should be at about 8pm UK time.
Hey guys, remember this? I wanna hold you to it.Xbox drinking game:1 shot for every time "social" is said1 shot for "online"1 shot for "integrated"1/2 for "media"
We've just been to the shop to stock up on supplies.
Xbox reveal bingo. Tick off if you hear: - "The future of..." - "It will change the way we..." - "A revolution in..." - "Never been done before" - "New and exciting" - "It's, like, totally better than the PS4"
Write your cards out now!
Not having much luck here. For the last time, here, linked, is the video of a young Don Mattrick.
It's Jay Allard before Microsoft's marketing team got hold of him!
On a slightly more serious note, there's the Xbox Reveal tent where everything will happen this evening. Tom Bramwell is there for Eurogamer.
Oh look, it's the MTV Xbox 360 announcement video from 2005. Listen to all those promises. Did you say changeable face plates? Holy macaroni!
Here's a more up to date picture of Don Mattrick.
Time for some next Xbox mock-ups!
What's with the pad pictures? There won't be any pads. You can control it with smartphone, tablet and Kinect, so who needs a pad?
Someone who's likely to feature prominently tonight is Phil Harrison, former boss of Sony Worldwide Studios, who now runs Xbox in Europe.
Harrison was synonymous with PlayStation 3 both on-stage and off. Time to find some photos.
That's him with hair, of course.
Does the 16:13 round Xbox talk like Steve Merchant?
Phil Harrison also appears to have enormous hands there.
Thank you @DrStrangelove for this wonderful video of Don Mattrick clapping! The best bits are his stares at the end.
That's Phil Harrison in full swing, next to the father of PlayStation, Ken Kutaragi. Harrison's defining moment was announcing the future that was PlayStation Home, of course.
The livestream of the next Xbox reveal will be embedded in this article at 6pm UK time, in case you're wondering. Don't panic!
And now, Bill Gates with a burger, as suggested by @orangpelupa.
He'll be watching.
If they go with Xbox Infinity, they can name the one after Xbox Beyond lol
If there is a next one...
Lots of name suggestions coming in. I hate Xbox 720, for the record, and don't think it'll be that. Xbox Infinity is a frontrunner - the on-its-side 8 could figure in the design of the console.
Xbox some-sort-of-gesture-name could be in the running.
What about just Xbox?
Just heard on the grapevine: Day 1 Oculus Rift, ships with the Premium package.
That's an interesting idea.
Will there be a video here? Or do I have to find it somewhere else?
There will. The video will be embedded shortly before 6pm UK time - so in about 25 minutes.
Hello from South East London! Tom's currently lining up to get into Microsoft's mega-tent, Bertie's plundering his photo archive and we're hooking Ellie's Xbox up. Coverage coming at you from all corners of the globe.
Is the feed actually available on the Xbox? If so I'll watch it on the telly!
I love that Oculus Rift rumour. What else are people expecting to see? Call of Duty, Battlefield and FIFA are dead certs, obviously. Can we expect to see anything a little more leftfield?
In case you missed it at the weekend, Chris Donlan had a look back at one of the best Xbox 360 launch games ( http://www.eurogamer.net/articles/2013-05-17-geometry-wars-retro-evolved-retrospective). Actually, screw that - it was the best of the launch games.
Would love there to be an unexpected pleasure like that tonight, but I don't know how well that would play in the mega-show that's in store.
Important update: TOM'S IN THE TENT.
Actually, that is super-important. I'm on the tea now, eyeing up a couple of beers for when it all kicks off. What's everyone else got by their side to power them through?
I, for one, want to know more about that tent. How many pegs did it take to get up? How long did it take to erect? Can I get one from Millets?
Thought I might pop in and say hello. Hello! I'm in the famous tent. Don Mattrick is posing for photos by the big green stage with chief of staff Aaron Greenberg in close attendance. Chris Lewis and Phil Harrison just wandered past my seat. Anyway, sorry for intruding on the fun.
Kudos to everyone watching the conference on their Wii U/PS3. STICK IT TO THE MAN.
Tom Phillips has called it - there'll be a Pizza Hut App 2.0. Don Hattrick crafting a Meat Feast before your very eyes on stage.
MORE ON THE TENT: It looks huge from outside but it's surprisingly intimate indoors. Sony had loads more people at the PS4 event in New York, whereas Microsoft has organised local streaming events in London and probably elsewhere.
Stream should be kicking in here very shortly.
Let's try again: The Call of Duty: Ghosts pre-roll featuring the "Xbox" name.
Is fifa14 getting shown?
Yush indeed. I'm genuinely interested in seeing how it looks on next-gen platforms. Sorry, I'm a monster.
10, 9, 8, 7......
I'm sat next to the editor of Official Xbox Magazine, Jon Hicks. He knows some things but he won't tell me them. He claims he doesn't know the name, but then he didn't blink when I suggested "Super Xbox"...
That's the countdown to the countdown finished, then.
Just spotted Peter Moore in the audience. He's sat further back than I am. IN YOUR FACE, PETER.
It's starting, I think. Don Mattrick is on stage geeing up the crowd. Enjoy.
Stick around after the conference, by the way. We'll have some more details on one of the game's being shown during the conference up on the site at 7pm.
Hello everyone! This is VERY EXCITING! I haven't been this excited since Sony showed off their new machine, except they didn't!
Is Mattrick reduced to warm-up act? Or is he just getting ahead of himself?
Right, that's it. Top's coming off. Lets do this.
The big question of course is what will it be called? Xbox 720: 12-1. Xbox 3: 25-1. Phil Harrison's Electrofunhub of Sexy Joy: 4-1.
I really, really like the idea of it being called simply Xbox. I was really excited when there were murmurings that the Wii U was simply going to be called Nintendo.
I would love to be in Sony HQ right now as they watch this.
Larry bringing us in to the show.
I suspect today will be the culmination of a long-term Trotskyite strategy by Phil Harrison. He will walk out on stage, kick over the autocue and shout "DADDY'S HOME"
There's a lot of body contact there. This is going to be one steamy conference.
Oh good, someone's said "emotion" already.
Kudo without the glasses! This is UNPRECEDENTED.
I always thought he had Cyclops-esque powers.
I've been going out with my telly for three years already. Never does the washing up.
Anyway, the Xbox is going to allow you to have a relationship with your television.
We're running a little behind here with the Xbox stream - bear with us!
"Emerging technologies" - tick that off your bingo card.
And we're back in. A look back at the original dashboard for Xbox 360, and a potted history of Microsoft's innovations. More on Xbox 360 coming soon.
But we're not here for that, obviously.
Has anyone else noticed that Don Mattrick never ages?
The ultimate all-in-one home entertainment system.
Simple, instant and complete. They're coming for your living room.
It looks like a Wii, Bertie notes.
The pad itself builds upon the original design, adding a Windows button.
And it's called the Xbox One.
They're leading with the machine itself, in contrast to Sony's PS4 reveal.
It's built to continually improve over the generation ahead.
And again it's about being instant, simple and complete.
And it looks very much like a set-top box. They're not really hiding what their aims are here.
I think it looks pretty hot, myself.
"Let me set up an aspiration." Is this stuff written for them, or does it just dribble out their faces?
The home screen looks like an evolution of the existing 360 dash.
And of course it reveals there's a new Forza inbound.
Xbox One will play TV! Just like the 360 does!
There's a snappy, quick change from function to function.
Switching between games and television happens near-instantly, and is powered by voice control. Spread your hands and grab the screen and you're back home.
Snap Mode allows you to run multiple programmes at once. Again, powered by voice.
And again there's SmartGlass functionality.
Skype, which of course MS acquired last year, plays a part, allowing you to do group video calls.
Sorry I disappeared for a few minutes there. I fainted at the prospect of being able to watch TV on my TV.
Xbox One, Kinect Two!
We're getting a rundown of the ESPN functions. Which is kind of hard to care about on this side of the pond.
The Xbox One gude will show you what's on TV.
A bit like the Radio Times, innit.
So this bloke's "Xbox Fantasy" is all about "DOMINAATE"? More like 50 Shades of Ssshhh never mind.
How will this filter down to us in the EU?
The Mindy Project! I'm not sure I would have chosen that to advertise this feature.
Marc Whitten, he of the magic and science, will show us how a set-top box works now.
Finding it a little hard to believe all this is going to work when we are sitting here with an Xbox, an iPad and a laptop and keep having to switch between them to keep up with this live stream.
There's an image of Kinect 2.0 for you there courtesy of Bertie.
5 BILLION TRANSISTORS! I bet Rich Leadbetter has more than that in a shoebox under his bed though
Plus, of course, the console and controller.
In amidst that was the killer: 8GB RAM
Plus USB 3.0, 500GB hard drive and Blu-ray.
Three operating systems in one! Because one operating system just isn't enough. That's why my car has six steering wheels.
There are three operating systems that work together. Which is where that RAM's heading.
1080p camera at 30fps for the new Kinect.
Rich Leadbetter would be doing a white weewee right now, if he hadn't already evolved to exist as an intelligent gas in space.
It's a wider field view camera - which should allow for it to be used in bigger living rooms.
Or normal ones, that is.
New Kinect will record the energy of emotion.
Hang on wait... This can only mean one thing... JUST DANCE 6!!!!!!!!!!!!!!!
On to the controller now - new d-pad, force feedback triggers.
And Xbox One will integrate with your smartphones and tablets.
Kinect will profile you and load your save. That's both awesome and terrifying.
New Xbox Live being introduced, and based on the existing membership.
360 had 3000 servers - and now it's 15000.
Wait - it's 300,000 servers for Xbox One.
Like the PS4, you can share footage.
Bigger matches with more players are possible - so we should finally see MMO-like experiences on the Xbox.
I want to live in a persistent world! As long as they have PG Tips and The Archers.
Andrew Wilson takes to the stage, and we may see our first game.
There's a new partnership between EA and MS.
Is that a huge microphone or a tiny misplaced bow tie?
Four games being developed for Xbox One - FIFA, Madden, NBA and UFC.
They're all coming out over the next few months. And EA will finally release an NBA game.
Sir. I may not know a lot about football games. But I find it hard to believe you will make anything "revolutionary" that has "14" in its title.
EA Sports Ignite's a new feature that will blur the line between the real and the virtual. I don't understand the rest of what is coming from Andrew Wilson's face.
Some American chaps tell us about sport. And now so does Messi.
Sport is as much about your head as it is your feet and hands, says Wilson.
This speech is useless without polygons
Xbox One will allow ten times more animation than 360 games.
I really haven't heard anything of substance come from this section.
FIFA 14 Ultimate Team's exclusive to Xbox.
That's huge - it's one of the series' biggest pulls.
And I've just been told it's only exclusive content. Stand down!
Gameplay time. There is more animation, but, well. It kind of looks like FIFA.
Phil Spencer, general manager of MS Studios, takes to the stage.
Phil Spencer's not wearing a jacket. A sweater will do for Phil Spencer. Phil Spencer may be kind of a big deal, but Phil Spencer is still one of the guys.
MS Studios are building new original games. Plus! There's old franchises being reimagined.
First up is Forza 5.
City tracks are being shown off.
Cars game! Oli and Martin just went from six to midnight.
The new McLaren stars, as does the old F1.
I hear John Hindhaugh doing commentary. The only quality thing so far in this show.
That's awesome news! He's a Radio LeMans staple. But I thought he was all about GT! He was at the GT6 launch last week.
NEW first ever experiences. Not new experiences. Or first ever experiences. NEW FIRST EVER experiences.
Remedy are up now.
And it's... Quantum Break?
A creepy live-action trailer segues into CG, with a ship tearing through a bridge.
Time is the fire in which we burn says the blurb. I would like to see the game running please!
Misread that title originally and am now massively disappointed, it's about time Scott Bakula was back on our screens
It's new IP - does that mean the end of Alan Wake?
Funny how they're not doing an Alan Wake 2. Almost as if I was right about that 7/10.
15 exclusive games to be released in the first year of Xbox One, eight of which are new IP.
YOU TELLEM NANCY TELLEM. Bet she's never heard that one before. Oh, she's borrowed Cammie Dunaway's white jacket!
Not the trousers though, after that incident with Reggie and the Bloody Mary.
Xbox will be a watercooler, Nancy reveals.
I don't think she means that literally, sadly.
Barbra Streisand's looking well these days. Halo, Dolly.
Bonnie Ross takes to the stage from 343 - but before you get your hopes up, I think this is for a new TV series.
Hang on wait - TWO WOMEN allowed on stage during the SAME VIDEO GAMES CONFERENCE? There's been some kind of mistake, call the police
Forward Unto Dawn 2!
Game of Spacethrones! Brilliant.
Spielberg's onboard. But he can't be arsed to be onstage this time round.
"I wish I could be there with you today in person, but I have to wait in for my Ocado delivery"
He started playing Pong in 1974 and hasn't stopped since.
It's called, simply, Halo the television series.
Oh go on, just do a quick one from Yentl
A game changing partnership. In the US, that is.
This looks like a relaxed natural scene.
A partnership with the NFL.
I'm not sure if MS knows they have a global audience.
I'd be more impressed if they were "changing the game of football" so radically that they made the players kick the ball AS IT IS SUPPOSED TO BE DONE.
It seems like we're building up to Call of Duty Ghosts, which will be the show closer.
The magic and science of television for you there.
But we're getting a release date!
Oh, no we're not - it's coming out around the world later this year.
There'll be more at E3 - and hopefully some games will be there too.
WORLD PREEEMYER! I love world preemyers!
Here it is - your first look at Call of Duty Ghosts.
MS keeps the timed exclusivity on COD DLC.
Eric Hirshberg, the last human speedbump.
I'd watch that TV show.
Never mind all this nonsense. WHEN IS XBOX GETTING CANDY CRUSH???
A look inside Infinity Ward - we'll be bringing you more on this in about 5 minutes on the site.
The writer of Traffic and the director of Syriana onboard.
Peeeeople... People who need peeeeople...
It's post-apocalyptic - and you're up against a new superpower.
Yes, it has a dog.
DOG ALERT. Hang on are they about to announce the new Call of Duty is being done by Peter Molyneux?
You will care about the dog, and you will love the dog. Where have I heard that before?
CALL OF DUTY: MOLYNEUX. I would pay upwards of eight pounds to play that.
You can leap over walls now in Call of Duty. And lean around walls.
Or how about Call of Doggies, where you play a German Shepherd having a nice bark
Dynamic fish n'all.
MP maps will be dynamic, with events like earthquakes changing their layout.
And you'll be able to customise your soldier.
So to summarise: TV, motion control, cars, American football, TV, Halo on TV, Streisand, dogs.
What time is Beyonce on?
Frankly at this point I'd be happy with Rylan.
A comparison between character models now. They'll have dirty fingernails in the future.
That is the best dog I have ever seen.
Hairy arms a next-gen feature.
Better dogs. Better arms. Better hairs. THE FUTUR HAVE ARRIVE
Boosted polycount, self-casting shadow. But yeah, that dog.
Finally, our first look at some Xbox One gameplay.
You can read our preview here - http://www.eurogamer.net/articles/2013-05-21-mocapped-dogs-exponential-polygons-and-a-mysterious-apocalypse-infinity-wards-next-gen-call-of-duty-ghosts
SICK BALLS, ADOLF
And with that, MS concludes its Xbox One reveal.
Well, that was certainly a thing.
One game shown running on the new console, and a lot about American TV shows.
There'll be more at E3. Including, we hope, a look at the launch line-up.
So that's it. You'll be able to Skype dogs playing American football while watching a Halo TV show powered by clouds. And having a wank.
We'll leave it at that for now. There'll be more analysis over the following day on the site, and Tom will be having at some of the execs trying to get an answer to all the questions left after that showing.
Tom snapped a pictured of the back of it. Note the HDMI in port, as rumoured.
