In an interview with CVG, marketing game manager Dax Ginn said that more titles were on the cards if the developer has "stories to tell".
"I mean I think as long as we're still enjoying it and as long as we feel we can contribute to the Batman universe... that's how it feels," he said.
"There's some amazing stuff going on with Batman all around the world at the moment and we feel as though we're making our own little contribution in the form of the Arkham-verse.
"So as long as we've got stories to tell. So long as we feel we can do that and do that really well.
"I don't know what's going to happen in the future but right now I feel like we're in a real sweet spot with the games that we're making, the opportunities that we have so I don't really want that to change."
Assuming Batman: Arkham City maintains the quality of its predecessor, we think it's pretty safe to say there will be more Batman games from Rocksteady Studios.
