Here's what Cliffy B has said regarding the Wii U recently:
Being raised on All Things Nintendo I will always I love all things Nintendo. I'll be watching the Wii U closely. I think Nintendo may have initially lost a little of their core with the Wii for a bit, honestly, and they seem to have realized this. I believe they also recognize that we live in a "multi-screen" culture hence the controller design. I played ZombiU at PAX and it was promising (even though the controls could use a little loving!) so we'll have to wait and see.
That first sentence without a pause made me laugh, I still remember how Cliffy B featured in issues of Nintendo Power as a kid. Epic Games once said the Wii was like a virus infecting the videogame industry, they've certainly changed their tune, haha. I wonder why. There have been rumours regarding a joint project between Nintendo and Epic Games, but we'll have to wait and see if there's any truth to it. After their work on Shadow Complex, a downloadable 2D Metroid would be nice.
