I think it could be fun, much like the Wii this would be something to 'turn on' during a party, instead of having to turn off when more than 4 friends come over.
It's disappointing that there's so many people here not willing to give it half a chance. If it's not unconfirmed list prices, it's lag on unfinished games, or multiplayer limitations on games better suited for a controller, or not being able to sit down...yet. Wish we could just wait for the damn thing to come out first.
Anyway, as usual, popular opinion on vgchartz is the minority of the mass market. I bet JRPG's would come out trumps in a poll of best genre here.
