A number of new domain registrations have sparked speculation after they were shared on the Resetera forums, as picked up by Video Games Chronicle. They include suicidesquadgame.com, gothamknightsgame.com, and suicidesquadkillthejusticeleague.com, all of which have been registered in June by MarkMonitor Inc. While the link to Warner Bros hasn't yet been confirmed, MarkMonitor Inc. is the same domain broker used to register wbgames.com.

WB Games Montreal, the studio behind Batman: Arkham Origins, has been teasing a new Batman game for months now with the slogan "Capture The Knight". This has led fans to assume that the Gotham Knights domain registration is tied to--and has revealed the name of--WB Games Montreal's new game.

There have been rumors of a Suicide Squad game going back to when the movie was first released, with a Kotaku report claiming that WB Montreal was working on one that ended up being cancelled. To date, aside from a few tie-ins with existing Batman games, the only Suicide Squad game released was Suicide Squad: Special Ops, a first-person-shooter released on mobile platforms.
