I'm interested in how much they will charge for the WiiU controller. The Wii had controller-itis with the wiimote + nunchuck + motion plus. At least the WiiU will re-use the Wii's controllers.
Also, how does the 3DS fit in the equation? If the WiiU controller works for standalone gaming, it could compete against the 3DS.
While not explicitly stated anywhere, it seems the Wii U only supports a single new controller, as they haven't ever shown more than one. It probably ships with it, so you won't need to buy it on its own.
