Square Enix recently announced that they would start releasing more and more information about Final Fantasy Agito XIII once Final Fantasy XIII is released in December. This strongly suggests that it will be the next title released under the Fabula Nova Crystallis umbrella.

It also suggests that Final Fantasy Agito XIII will be released in 2010, in Japan at least, as Square Enix seldom promote their products way ahead of time any more. Hype for Dissidia: Final Fantasy started around six months before its final release, and the same has happened with Kingdom Hearts Birth By Sleep.

It would be logical to assume that the game won't come in the first half of the year, but it could easily arrive in Q3 or Q4 of 2010. Either way, Square Enix are sure to announce an official release window towards the start of next year.

I hate when S-E does this kind of stuff. We have been waiting for FFXIII since 2006, i hope that with FFXV they just show it at maximum one year before the release, and not 4 years before!
