I suddenly gained an interest for UMvC3, too. The only fighters I've ever played are this and Mortal Kombat 9, so it'll be very new to me. My copy should arrive tomorrow, and I've been extremely excited for it. That's after two mistakes on the delivery people's part delaying my ability to get the game, too, haha.
