Compliments of an Amazon listing, we now know what the Super Smash Bros. Wii U bundle will look like. It consists of the game, a GameCube controller adapter hub, and a branded GameCube controller for $99.99.
I think I'm going to pick the hub up at least, so I can bust it out for Smash parties later this year. It'll be BYOW -- Bring Your Own Wavebird.
