Videogaming 247 says it's been told by Namco Bandai US that Eternal Sonata on PS3 won't be leaving Japan. A spokesperson for the publisher tells the site that the game has only been announced for Japan and it has "no plans to release the game on the PS3 in the US at this moment." Of course, in the never-ending battle with PR semantics, "at this moment" could mean the game will eventually be announced for other territories.
Eternal Sonata's official Japan-only PS3 status might explain some of the strange things that happened late last year when the game was announced for the PS3 on the ESRB site (pictured above) and on Namco's own US site, only to be removed sometime later.
