I think so, yes. Probably not for a while though.

I enjoyed Dissidia but I must admit it didn't really make a big impact on me, which is strange because I remember buying Ehrgeiz for the exact reason of being able to fight as Cloud etc.

The reason I mention this is that for me 012 came out really quickly after the original and considering the amount of content to collect, it kinda jaded me a bit. I got them both on release so had plenty of time to play them but they could never hold my attention long enough.

So yeah, if a new Dissidia comes out, as someone in my position, I think it will be at least a couple of years and possibly for PS4 and Xbox One. Vita is fine in Japan, but Sony is slowly making it redundant as a game machine in the west so I am sceptical as to whether or not SE would attempt another handheld entry, instead choosing to go all out and grab the home console install base (similar to the remake of Type-0).
