I played a demo of it at the New York Comic Con and from what I played, I didn't like it.
It's trying to be like Isuka with two screens. I kept trying to jump towards my opponet and I ended up jumping onto the platform above me. It was really annoying because I didn't know were the hell my character was till I looked on the top screen.
The game also suffers the same turning crap that Isuka did, I kept swinging at air while the computer was beating the crap out of me.
I'd say skip it and import Bleach DS. It's a better game and the multiplayer is a lot of fun too.
