Thats what they said with Arkham City. Then, now comes Arkham Knight.

Sigh. I hope Rocksteady will keep their promise this time. Enough is enough, maybe work on something else from DC universe as the universe does have a lot of interesting content.

There are rumors saying that Warner Montreal who made Origins might work on a Suicide Squad game where you might play as Deathstroke along with 5 other villains being hired by the government to do jobs that Batman could not finish. Might have coop too, considering these villains work together.
