That _screenshot_ has cut out heads. It looks cool in a still, but I have to think it would be kind of distracting and gross in motion. Quick cuts from profile to side view, that sort of thing. I hope that isn't the case.
Honestly, I know they won't do this, but the game would have potential in a Mii style. Make every player using the Mii engine. Allow for some "cheating" here and there and I think it could look really cool.
If it is 3-on-3, here's hoping for full six player online play.
