THIS IS NOT A THREAD ABOUT WHICH CHARACTERS SHOULD BE IN DISSIDIA 2

Now that most of us have played this game pretty thoroughly, what are you hoping to see in a sequel (if they ever make one) gameplay wise and other things like whether is should be on a real console or stick to the PSP?

Any characters that need improvement? Nerfed? Changes to the Summon system? Battlegen? Equipment system? Music?
