Square Enix just released the closed mega theater trailer of Dissidia 012[duodecim]: Final Fantasy. It begins with the Warrior of Light standing in a foggy area alone, but quickly jumps into footage of Lightning and Kain.
Tifa encounters Sephiroth at the end and strangely enough she doesn’t recognize him. She asks who he is. Sephiroth says he is an enemy and Tifa, apparently aware of the Chaos and Cosomos conflict, identifies him as a Chaos fighter.
Dissidia 012[duodecim]: Final Fantasy comes out in Japan next spring. Square Enix confirmed the PSP game for North America and Europe. A release window for the West has not been announced at this time.
