Bob Harras and Bobbie Chase answer fan questions at CBR, and promise more diversity in the New 52:
I think that you’ll see we have a wide variety of genres coming up. We haven’t given up on launching books like “Animal Man,” “Swamp Thing” and “All-Star Western” because we like the unique flavor they give the New 52. That is not ending, and in the next few months you’ll see some titles that are not connected to the core franchises that mal-adjusted was talking about. And there may be some titles that will be! [Laughs] But we’ll still keep different things coming out going forward.
Specific titles/characters “discussed” as part of this may include the Creeper, Vigilante, Gotham Central, Lobo, Kamandi, New Gods and Adam Strange.
