Square Enix is bringing back its ultimate crossover fighter for another round on PSP. This week's Weekly Shounen Jump confirms a Dissidia Final Fantasy sequel, which uses some expected unconventional Tetsuya Nomura naming: Dissidia Duodecim: Final Fantasy.
The magazine shows playable Lightning from Final Fantasy XIII and Kain from Final Fantasy IV. We couldn't see any further details beyond this.
The wait for more info shouldn't be long. In a Tweet earlier today, series director Tetsuya Nomura confirmed that one of his secret unannounced games would be playable at next week's Tokyo Game Show. It's likely that Dissidia is that very game.
Dissidia Duodecim is scheduled for Japanese PSP release in 2011.
