Played it on my friend's PS3, it took some getting use to. At first, 3/5 I want to do a shoryuken, I do a hadouken instead. I wish I had video to show this hilarity. After some practice, I was able to rectify this small input error.
But for other moves, its real finicky. I use to be able to do Guile's flash kick on command, but in this version, it seems to do it when it feels like it.
I like the online play though. Match's are easy to get into, my move's don't lag (compared to brawl where you had to telegraph a move .5-1 second in advance), and if there is some lag, it doesn't freeze for a sec, then cuts to someone getting a beat down.
Shame there's no Wiiware version, but I'll still recommend this to all my PS3/360 owning friends.
