Rocksteady Studios have announced that Batman: Arkham Collection will be releasing this September, with the bundle including Batman: Arkham Asylum, Batman: Arkham City and Batman: Arkham Knight. Batman: Arkham Origins is unfortunately not included in the collection, likely due to the fact that the game was developed by Warner Bros Games Montréal as opposed to Rocksteady.
The collection will naturally be including the remastered versions of Arkham Asylum and Arkham City, which were originally included in the Return to Arkham collection released back in 2012. Physical copies of the Arkham Collection will be packaged in a steelbook case, with the PlayStation 4 version receiving the exclusive Earth 2 Dark Knight skin.
Batman: Arkham Collection is releasing for Xbox One and PlayStation 4 on 6th September 2019.
