Considering it's got all the grunt of the 360 focused on basically two character models, you'd want it to look good

I hope the iron out the niggles that showed up in FN2, like the horrible animated menus you couldn't skip, the stupid white flash in the replays when you land a haymaker (like 90% of the time) and the dorky commentator that calls all haymakers haymakers. Oh, and a less stupid parry system that doesn't give the AI a stupidly huge advantage.
Other than that, I like the system

It will be one to watch - perhaps a Rev version is coming? Hmm...
