SSBB uses the same controls as the gamecube, theres no new controls for the wii.
Taken from IGN.
Under the direction of series creator Masahiro Sakurai, Super Smash Bros. Brawl will feature classic, GameCube-style combat -- not Wii-style motion-controlled combat. That means players who prefer to play the game with the traditional control setup can look forward to using the GameCube control-style they're already accustomed to.
"We found that trying to implement too much motion-sensory functionality can get in the way of the game. We're looking at keeping the control simple, as it has been," said Sakurai. "The Wii hardware has sockets for the GameCube controller, too. So I'll just say now that you may not want to throw away your GCN controller yet."
