Not only is one of Nintendos most loved games soon to arrive on the Wii U, but youll also be able to play it using one of the game companys best controllers. An officially licensed adapter will let you plug in up to four GameCube controllers when playing the next-gen iteration of Super Smash Bros. As Joystiq points out, we dont know if therell also be support for Nintendos wireless Wavebird via the same piece of kit, or whether GameCube controllers will work with other Wii U titles.
