UPDATE: NetherRealm Studios chief Ed Boon has suggested it's unlikely an Xbox One version of Injustice will be released.
Some have speculated that the PS4 version of Injustice, announced today, is a timed next-gen exclusive, and will eventually launch on Microsoft's console.
But, according to a series of tweets by Boon, this seems doubtful.
"Please tell me it comes on xb1 so I can sell my 360," DLG1202 tweeted at Boon. Boon's reply: "Um.... I wouldn't sell that 360 copy..."
Then, after "C2CA_KILLA" pointed out: "Injustice sold the most on xbox. So tell me the logic behind no xbox one version?", Boon replied: "Again... not as simple as that."
It was a similar response to questions around the lack of a Wii U version of Ultimate Edition - despite the original version launching on Nintendo's console: "It's not as simple as that."
Eurogamer has asked Warner for comment.
ORIGINAL STORY: Warner has confirmed that fighting game Injustice: Gods Among Us is coming to PlayStation 4 - but not Xbox One.
The Injustice: Gods Among Us Ultimate Edition launches for PC, PlayStation 4, PlayStation 3, Vita, Xbox 360 and PC on 29th November 2013. Microsoft's next-gen console is nowhere to be seen.
Nor is there mention of a Wii U version - despite the original game launching on Nintendo's console.
The Ultimate Edition includes all original game content as well as all DLC, which Warner said is worth £79. The Ultimate Edition's suggested retail price is £50 for PS4, PS3 and Xbox 360, and £30 for PC and Vita.
The DLC includes characters Lobo, Batgirl, General Zod, Martian Manhunter, Zatanna and Mortal Kombat's Scorpion re-imagined by DC chief Jim Lee.
There are also more than 40 extra character skins and 60 S.T.A.R. Labs Missions, originally offered as DLC, now available from the start of the game.
The PS4 port was created by High Voltage, and uses the DualShock 4's Touchpad functionality, the console's video sharing and streaming, and links to players' PlayStation Network Feed page during match wrap-ups and pause menus. High Voltage, maker of The Conduit, also made the PC version.
The Vita version was developed by Armature Studio, creator of the Vita and Nintendo 3DS Batman game due out later this year. It has touch controls for mini-games in the story mode and S.T.A.R. Labs Missions, Ad-hoc and Wi-Fi multiplayer, collectible hero cards, and all DLC released to date.
