Siliconera is claiming they’ve received tips that state that Castlevania: Harmony of Despair is coming to PlayStation Network. The 2010 Summer of Arcade Xbox Live Arcade game introduced co-op multiplayer to the classic action-platformer to mixed reviews.
It’s possible that the Xbox Live Arcade game had a timed exclusive, and that Harmony of Despair will be released a year later for PS3 owners. It’ll probably be announced at E3, either at Sony’s conference or from Konami.
