NIS America have already confirmed Atelier Rorona for a fall release, however, they haven’t said much past that. Today, a new GameFly listing suggests that the game is currently scheduled for a September 30, 2010 release.
Sounds about right to me. GameFly is usually pretty accurate with these leaks. Remember Star Ocean: The Last Hope International for PS3?
Looks like the game is titled Atelier Rorona: The Alchemists of Arland for its western release rather than Atelier Rorona: Alchemist of Arland like the Japanese version.
