Batman: Imposters coming to XBL?

Could there be a new Batman game in the works? Rumours have been spreading round the web of an Xbox Live title called Batman: Imposters being in development.

Initially it didn’t seem like much ground was beneath these claims, but Superannuation has dug up a few Warner Brothers owned domain names:, and Seems like something is up, doesn’t it?

Both Red Hood and Hush are Batman villains that have their identities shrouded in mystery, making them a good fit for a game titled Imposters. Perhaps Warner Bros is planning some sort of downloadable prequel to Batman: Arkham City?
