they created this motionless controller for the new system

not sure if it is the primary controller or will work alongside wiimotes (two "primary" controls perhaps?), probably depends on the game. (i hope to god the gamepad is primary though)
along with that, they're also making this which I assume will replace the classic controller

if anything, i'd expect third-party multiplatform games to use it
more information about the Wii U is coming out in two days. price and release date too, i believe.
