If they're taking this long with it I'm sure it'll be a DOA5U level update, with a few new moves here and there for the characters (along with the stages and characters of course) :)
Something cute I've been doing:
If you land a 4p, go into 4k and this guarantees (I think) a 3p launcher from the sitdown stun. On lightweights you can follow up with 8ppp p+k into air throw for 109 damage altogether.
