From GameWatcher: “It’s been a long time since Rocksteady’s Batman: Arkham Knight, and even longer since the other Batman Arkham studio WB Montreal – creators of Batman: Arkham Origins – had a release. Now, however, the studio is teasing a new game reveal or release for 2019 – could it be the next Batman Arkham game?
Batman: Arkham Origins came out in 2013, and since then the only release from WB Montreal was the Batgirl DLC for Batman: Arkham Knight. 2019 may finally bring the studio’s next game, and it’s looking very likely to be a Batman title.”
