Well now I really am debuting this game. Kevin Conroy, the voice actor for Batman (and Batman: The Animated Series, Justice League, JLU, Batman Beyond and Injustice) will NOT be returning for Batman Arkham Origins. I know this shouldn't effect my decision, but that man IS Batman to me.
Oh, and this was reported on IGN but I'm on my phone and can't provide a link right now.
Remember. Never goto the Library without your shotgun.
Terrible news. Batman TAS is THE Batman cartoon GOAT. His Batman voice felt right, I hope the next guy they cast copies it well. Hopefully we find out in a trailer. All great games eventually take a step back, this may be what happens here.
