Thought I would chime in on this also...
As has been previously mentioned, graphically it's the definitive version--characters and environments are much more smooth and detailed. I put the Japanese version back in afterwards and there is a noticeable difference.
The online community is very small. I played for a few hours and ran into the same people over and over again; on several occasions I didn't even find a match.
The overall speed of the game (i.e menus, selections, option settings, loading etc...) is much improved.
Twitch streaming was flawless and simple. I had my LGP on standby just in case ( I was recording the system menu and setup prior to the game) but I didn't need it.
My custom stick was not recognized in either PS3 or 360 mode
After all this, I'm on the fence if I'm going to keep it or trade it in (it was part of a Target B2G1). While the graphical enhancements, speed, and twitch streaming are impressive the lack of community and no arcade stick support are potential deal breakers to me. Arcade stick support is definitely coming--particularly with GGXRD being announced for PS4--but I'm not confident in anyway, shape or form that NRS will patch this game for stick support since Sony more or less said it's up to the developers to implement this.
With a 100% trade in bonus this week at Best Buy I've got a lot to think about...sorry for rambling but I always read everyone else's comments and learn so much I thought I should give something back for a change.
