There was some confusion over the weekend over a comment made by Kevin Conroy about doing a lot of voice work for the next Arkham game. Turns out he's referring to one not yet announced. This popped up on twitter, then was deleted soon after:
I've loved the Arkham series so far but am starting to worry they're going to run it into the ground. Hopefully Rocksteady is back for this next game and will be changing up the formula a good bit.
