Dissidia Duodecim Final Fantasy possible characters

From VI there are only two characters that I would love to see in the game; Gau or Edgar.
I do hope that Vivi gets to be in the game; but he may be passed in favor of Steiner or Beatrix. Even though I would prefer Vivi since Cosmos could use a bit more magic casters; since mages seem to overpower chaos.

a lot of people want vivi for ff9 so he does have a good chance of getting in, people are suggesting that his hp attacks could be 2 do whith his focus ability, such as he charges up his attacks and depending on how long u charge up the attack is more powerfull (kind like what terra does whith meltdown)
