According to the company’s official website, it appears Bandai Namco are more aware of a PlayStation 3 version of Eternal Sonata than previously stated.
Just months ago, company representatives stated they were "not aware" of a PS3 version of the upcoming title; however, new evidence has appeared that seems to debunk this statement.
The game's official listing on Bandai Namco’s site now has it listed as a PlayStation 3 game. The release date is TBD and is listed under platforms quite conveniently.
Eternal Sonata describes the adventures of famed composer Frederic Chopin as he explores his dream world filled with wondrous characters and beautiful environments. In a land where music influences both combat and exploration in mystical ways, Chopin sets out on a journey not only of self-discovery, but also of serenity.
