Dissidia Duodecim Final Fantasy possible characters

I honestly don't believe this Dissidia will deal with crystals. Atleast if it does, not in the same was the first Dissidia did.

Dissidia 1 dealt with using these crystals to bring an absolute end to the war. Since the new Dissidia is a prequel, it can't bring an absolute end to the war, because the first Dissidia proves the war didn't actually end.

So likely Chaos side storymodes will focus on defeating the heroes, since in the opening text for the first Dissidia it said 'Those who answered Chaos' call created an inexhaustible force, and one by one the warriors of Cosmos began to fall. Now only ten remain.'

Likely the new Dissidia will end in the deaths of every character not from the original.

This is just my speculation, though.
