Warner Montreal developed Batman Arkham Origins, a great approach to the RockSteady vision of the bat. Arkham Origins has -probably- the best story in the series and wonderful boss encounters. The Canadian’s studio could continue their work with Batman.
According to previous rumors, the developer was working on two new games: a new Batman game and a Suicide Squad title. A new rumor states that Warner has cancelled the unannounced Suicide Squad game and they are focusing their efforts on the new Batman game.
This new Batman iteration could change Bruce Wayne for Damian Wayne. Coming back to the issue, the Suicide Squad title could have been in development for two years and supposedly was going to offer a cooperative formula to the players.
