It would have been neat if it were completely Wii-styled, with a clear A button, all other buttons white, white sticks (the control stick, of course, having only one ring), a D-pad with blue lines instead of arrows, and a Wii logo where the GameCube one would be. Of course, you'd look silly using one of those to play a GameCube, but what are we all using our GameCube controllers to do these days? Brawl.
Know your priorities and do what's most important, Jesse. If you decide you shouldn't get it now, scoot the couch closer to the TV.
