Of course a new machine will be more expensive than an old machine, that's irrelevant.
Look, I'm not saying the Wii U has had an amazing launch. But it's all about software, ultimately. I haven't actually got a Wii U yet, but I know I will one day - when the big hitters come. And I'm sure many will do the same.
And as for the new machines... They're not going to be cheap at launch, plus software will be expensive to make and take longer to develop. I can be you now a game won't cost less than current Xbox/PS3 ones either.
I think anyone expecting major new releases on a week-by-week basis from launch is going to be sorely disappointed. Publishers will dip their toes but, as with all launches, it'll take time for a steady stream to form.
There's also the issue whether anyone but the hardcore will be able to see the value in the upgrade - I think many will find it hard to see the graphical uplift - but that's a whole other issue...
In short, I don't think that the success of the next Xbox/Playstation is a given. I certainly think they'll do okay, but will that be enough to give publishers the return they need to make more games?
It's a scary time for everyone.
New games will do the usual thing of being £5-10 more at the start then return to usual. Worst case is you wait a month and you'll be paying £30, 6 months and it'll be £10 just as it is now.
The cost to developers won't be that much more, tech moves on, tools and techniques get better. If it does go up then they might go back to ideas rather than art and 3 hours of shit cutscenes that everyone hammers the x button to skip anyway.
I came in like a wrecking ball. Yeah, I just closed my eyes and swung. Left me crashing in a blazing fall. All you ever did was wreck me. Yeah, you, you wreck me.
