lol... you also need to remember we said that years ago. We're knocking on the door of the next generation now... too little too late.
And we've already seen PSP do similar functionality pretty damn well, so PS3/Vita shouldn't have any problem at all. Vita by itself can do a lot of what Wii U can (games where you move the controller around to see a different view of the world around you, for instance). Vita pretty much is a Wii U controller with a back touchpad and a heck of a lot more processing power. I don't doubt it could handle it. What I question is if they'll actually do it.
Even then, I saw potential for some cool gameplay types, but again Nintendo is banking on the controller selling the system and I just don't see that happening. It's a gimped PS3 (no blu-ray) with a gimped Vita for a controller...
It's not "fuck nintendo" at all, it's more "nintendo didn't sell me on this one with what they've shown so far".
