Suprised this hasn't been posted yet:p. Missed the timer personally 'cuz I was outside, but here ya go:
Some pretty memorable, defining moments shown. Charlie sticking his hand in, Dojima being a boss, and my personal favorite, 0:30. Where you see the critical hit/knock down flash thingy . The art is a little shakey at times, but the animation shown so far still does look pretty good.
And lol at the people who honestly thought this would only cover Yukiko's arc. That would be a terrible and dumb idea.
There's a release date, too. October 2011
