While there's still no long been rumoured to be a Superman game. But is that what's really happening?
In June last year, several job listings were spotted at Gotham Knights and Batman: Arkham Origins studio WB Montreal that mentioned "a third-person open-world action game" and "a new IP, triple-A title". While a new IP was suggested, it could be a Superman game or another title that's unconnected from previous DC Comics games – like the Arkham series.
Now a new job listing has appeared for a announcement last month of a Wonder Woman game. Unfortunately, in this instance, there may be a complication.
As pointed out by James Sigfield on Twitter, WB Montreal also s other Warner Bros studios, so it's entirely possible that this new title isn't specifically the studio's next game. In fact, WB Montreal has already been working on its next game for a while, but it's quite possibly on hold until the studio finishes Gotham Knights – so, we'll probably have to wait until after Gotham Knights releases before we find out more about the developer's other game in production.

At the moment, the only game from WB Games where Superman is guaranteed playable is the publisher's Suicide Squad: Kill The Justice League.
