Gilgamesh is hardly a real threat... he's more of a handicap for whichever side he's trapped on so no worries. Besides, its not like it's fair most of the villains have to face two heroes instead of one. Hell, XI and XIII still don't have Chaos counterparts.

Being the pessimist that I am, I have lost hoped that IX and VI will get new characters and that has really made this game have a bit of a sour taste for me.

Not to mention that I now have to deal with Yuna being in the game (guess who I'm going to kill over and over) and the prospect of Lightning stealing most of the spotlight in the plot, seeing how she's usually front and center in every new trailer and the game is treating her like the main character. I get Kain, Laguna, and Gilgamesh but overall I haven't been impressed with the choices for new characters. Made worse by two of my top fave FFs being possibly passed over.

We still have a month left but SE hasn't even officially confirmed Gilgamesh and Prishe in publication not to mention most of the new characters were revealed alongside their numbered counterparts(II, V, and XI haven't been featured yet, whereas VI and IX have been featured recently). It's looking a bit glum for VI and IX fans.

I can only hope for a last minute reveal or a later DLC but from some of the staff interviews, it sounds like Dissidia Duodecim has reached the PSPs limits. The director commented that in order to add any more characters and content they would have to move to more powerful hardware. (PSP2/3DS or possibly console). So the possibility of cramming a new character in by DLC doesn't sound hopeful especially since the team has only mentioned Original Missions, and alternate costumes as DLC.
