Riight so Square decided to make a sequel to Dissidia. Theres limited info on this so far but it seems decent enough.

Confirmed new characters are

Kain: FF4
Tifa Lockheart: FF7
Lightning: FF13
and this is just a rumour, but Bobby Edner (Voice of Vaan: FF12) hinted he was doing a voice role for Vaan on twitter, so maybe Vaan will be a new PC.

New stages are introduced. A new story mode. CHAOS story mode (About damn time)

Also some bad guys from Dissidia are now good guys, I believe Golbez, Jecht and Kuja.

New costumes. New moves and revamped combat system.

Oh and a new assist system.

All in all, im pretty excited for this. Can't wait.

Sounds awesome!! Lightning FTW!!

the first one was a great game, now that tifa's in...expect youtube vids just camera whoring her *physique*.

we should do ad-hoc party for this

indeed we should

isn't this game going to be infrastructure o.O F AD-HOC

no clue.~~~ =3

I'm pretty sure I read somewhere that its infrastructure

UPDATE:

2 More characters revealed. Both also makes no sense what-so-ever lulz.
