How is the animation, much different from SC III?

So after a few hours with SC IV, I think it's safe to say that it is an excellent package.  I've only been going through the story mode to get acquainted with all of the characters again, so I've yet to even touch on the Tower of Lost Souls or Character Creation.  The graphics are excellent, and the character models are very good.  As far as the new characters go, I've only used Yoda and the Apprentice; both have their positives and negatives.  Yoda can be a real bitch though, and the Apprentice has some nice moves but I don't see myself playing as them too much.  I think it's safe to say that after the time I've spent with it, this is a game I will be playing for quite some time.

Side note-If you are playing the 360 version without an  arcade stick, good luck with that.  I would track one down immediately.  Amazon has a Hori SC IV themed stick for $59.99--It looks to be the same model as the EX2, which is what I've been using.
Also, if anyone wants to play some online matches feel free to send me a msg on xbl or a pm here.
