Okay, wow. So I wasnt hyped for this AT ALL, since I rarely play SFIV any more. But seeing the new moves and costumes makes me more interested. Just seeing Fei Long do the 1-inch punch got me excited. But, Im guessing the costumes wont be editable like in Tekken. I think if they had customizable costumes it would give SSFIV more variety. But, this still looks freakin awesome.
