Bah, it's apparently a black male and most likely someone we already know. Not exactly a lot of candidates in the Batman books. Lucius Fox, Black Spider, and Michael Akins are unlikely. Considering Black Mask "killed" Orpheus, creating a link between the characters, and the new Black Mask's plan was apparently to start a gang war hurting Penguin and Two-Face (sort of like what happened in War Games) Orpheus is most likely candidate.
