He's dead wrong on the not launching this year part, but he could be right about the Wii U not necessarily turning around a sluggish game market.
It's basically just another 360/PS3 type product, just with Nintendo franchises on it. I don't know if it's necessarily a game changer. Maybe people will go nuts for Nintendo Land, but it's just as likely the reaction could be "well I already have a PS3/360, why do I need another system that has many of the same games?".
