This could be nothing. But it could be something.

Accepting an award as Character of the Year at tonight’s Spike TV VGA’s for Batman: Arkham City, the Joker voiced by Mark Hamil held up a script titled “Batman: Arkham World,” before quipping “Woops. Spoilers.”

So what does this mean? Are Rocksteady already at work on another Batman game? Who knows? But it would make sense. We’ll keep an eye on this and see where it goes.

For now, this is a major rumour.
