Whelp Nintendo, take all my money. I will gladly pay to use my gamecube controller with the new smash bros.
The Nintendo 360 controller would be fine, but it's still a new controller. I'm much happier with my familiar layout and feel of the gamecube controller.
EDIT: Oh and i'd like to point out that there's very, very little chance the adapter will cost more than 1 WiiU 360 controller. WiiU has no gaems, I don't need a controller for no gaems. So i'll buy the much cheaper adapter that lets me and my 4 gamecube controllers play the new Smash Bros instead of buying 4 Wii60 controllers. Mad savings.
