When both of these games were announced they were mobile phone titles designed for Japanese cell phones. Now The 3rd Birthday, a sequel to Parasite Eve with Aya, and Final Fantasy Agito XIII are in development as PSP games. The 3rd Birthday is scheduled to come out in Japan next year and it will probably come to North America too. Square Enix trademarked the 3rd Birthday months ago so chances are good. We’re nearly guaranteed to get Final Fantasy Agito XIII whenever it comes out in 2010 or later. Two PSP games from Square Enix are already scheduled in 2009: The 3rd Birthday and Kingdom Hearts: Birth By Sleep.
