Kotaku, via Dengeki Online, reports that the upcoming PlayStation 3 version of Eternal Sonata will feature additional content not found in the recently released Xbox 360 version.

Although they'll have to wait considerably longer to get their hands on the game, PlayStation 3 gamers are promised two additional playable characters (Serenade and Prince Crescendo, both are non-playable in the Xbox 360 game), each also gaining some new story sequences.
