Variety has word on what's going on at DC Entertainment, saying Rocksteady's follow up to Batman: Arkham Asylum and Batman: Arkham City will be a look back at the Silver Age of the 1950s: "New, highly stylized title is being developed as a prequel that revolves around Batman's first meeting with the Joker. It's based on the Silver Age of DC's comicbooks from the 1950s when the Caped Crusader teamed with other heroes like Superman and founded the Justice League of America." Thanks VG247.
