Kevin Conroy, the voice of Batman in the Batman: Arkham series of games, has said that there are currently no plans for another Arkham title. The last release that we got from developer Rocksteady was Batman: Arkham Knight, which launched back in 2015.
Now before we put complete faith in Conroy's words, we first need to consider a few things. For starters, we have to question just how much Conroy knows about the production of the games. He's obviously a fantastic voice actor for the Dark Knight, but we doubt that he can speak for the bigwigs at Warner Bros. That said, he may have heard something and he's merely passing that message on. Who can say?
On top of that, in the footage provided by Twitter user @KAOTIC24, it's perhaps a little difficult to determine whether Conroy is actually being serious, or whether he's laying on some thick sarcasm. We like to think that it's the former, but mention of "they made literally billions of dollars on those games, but there's no plan to do another one", may seem a touch sarcastic to some.
Given the success of the series, we could absolutely see Warner Bros. getting someone to pump out another Batman title, regardless of Rocksteady's involvement. But, as always, we'll have to wait and see to know for sure.
