During a Q&A panel at the Dallas Comic Con, Conroy said that "We've been working for about nine to ten months on the next Arkham. We all signed these contracts that we weren't allowed to talk about this. The studio likes to completely control the roll out of any product, so they don't like any of us to talk about anything. It's now been announced."
This led people to assume that he was in fact appearing in Batman: Arkham Origins. That game, developed by WB Studios Montreal, has already been announced, after all. But, on Twitter just now, the voice actor has clarified that he didn't mean that game at all.
"Confusion in Dallas! I am in new ARKHAM GAME coming soon, NOT ARKHAM ORIGINS coming this fall," he wrote. Interesting! Could this be what Rocksteady is secretly working on while WB Montreal creates Arkham Origins? A next-gen Batman, perhaps?
At Dallas Comic Con, Conroy teased a little more about not-Arkham-Origins. "It's an unbelievable game. I still can't say anything about it. You don't want me to anyway because I'd ruin it for you. But it's amazing. It's a huge, huge cast and a big story. It took almost a year to write and put together. They've been working on it for a long time."
