Atlus cleared up some details on the release of Persona 3 today. Weve seen teaser ads on Atlus official site with a June 2007 release date and now Atlus sent an announcement that the release date is official. However, the North American release isnt going to be the extended Persona 3, Persona 3 Fes, that Japan is getting in April. Its a little disappointing since we got Shin Megami Tensei III: Maniax as Shin Megami Tensei: Nocturne. However, Persona 3 Fes is also being sold as an append disc. Perhaps Atlus is going to sell the extra content at a later date. While it might seem like Persona 3 is coming out late, the Japanese PS3 backwards compatibility list states the PS2 game has no problems on playing on a PS3. So even if you sell your PS2 you should still be able to play P3.
