Kevin Conroy, who lends his pipes to the dark knight in Batman: The Animated Series, Arkham Asylum, and the upcoming Arkham City, reckons that last one will see multiple DLC packs.
"The gaming now is a big, new thing. The thing about Arkham City is that it’s going to be an ongoing game," Conroy told ComicBooked.
"You’re going to be able to download future episodes of it, so it’s going to be going on for quite a while. I’ve been recording it for a while. So that will continue."
Rocksteady hasn't made any announcements regarding Arkham City DLC, although Arkham Asylum did front a few challenge maps.
Batman: Arkham City is due on PC, PlayStation 3 and Xbox 360 in October, with a Wii U version to follow.
