Since the release of last year's Batman: Arkham Knight in 2015, fans of the series have been clamoring for "remastered" versions Rocksteady's first two titles in the series, Batman: Arkham Asylum and Batman: Arkham City. Earlier this year it was announced that fans will be getting everything that they wanted, but at the same time, the announcement was largely disappointing. Return to Arkham won't include Batman: Arkham Origins, which Rocksteady did not develop, even though Virtuos Games will be developing this remastered package.
Secondly, the game was meant to deliver huge visual advancements and improvements since the original games were on PlayStation 3, Xbox 360, and PC. However, when comparing the screenshots, Return to Arkham were missing many of the lightning effects and texture details that were prevalent in the original releases.
This week, WB Games has announced on their forums that Batman: Return to Arkham will be delayed, "to give the team at Virtuos Games additional time to deliver a polished Batman Arkham game experience. We do not have a release date yet and will be sure to communicate that once we are sure the game will be ready."
