I have a feeling SSBB will use multiple control schemes...one using Wiimote/nunchuck, but with traditional-like controls (maybe some motion thrown in, nothing vital), classic controller, and GC controller. That way people don't need to buy a controller, cause they're bound to have one of those. But yeah, many games could use the Wiimote/nunchuck traditionally...it's basically a two-handed controller without a second analog stick.

Bet with disolitude: Left4Dead will have a higher Metacritic rating than Project Origin, 3 months after the second game's release. (hasn't been 3 months but it looks like I won :-p )
