I like the new Wario look and can be a good thing that is his main costume, but I really hope that the classic yellow costume will return.
Anyway, the alternate costumes are one of the little things that are missing in the first two SSBs......when I've seen Wario in the first video I thinked that the alternate costumes were a certainty (it is the right word?).
I did it too but only once I think...
