At the end of the trailer for the Super Smash Bros. Invitational, Nintendo surprised fans by showing off a new GameCube controller adapter for the Wii U. Yes, you will soon be able to use your old GameCube controllers on the Wii U.

The trailer can be found at the end of the post but the images of the adapter can be enjoyed right now.

There is virtually no additional details right now on how fans will be able to get their hands on one of these. There was no price mentioned either. With E3 just a handful of days away, it's possible Nintendo will spill the beans there.
