Co-operative vampire hunter reunion, Castlevania: Harmony Of Despair, is coming to the PlayStation 3 after a period of exclusivity on the XBOX 360

That's according to Siliconera, which cites "two different sources" for its story.

The multiplayer spin-off commanded mixed reaction on the XBOX, settling with a reasonable (but hardly outstanding) Metacritic of 67. Expect this announcement at Konami's pre-E3 event later in the week if Siliconera is correct.
