There are more pre-announcements the week before San Diego Comic Con every year, it seems, and here's one of the bigger ones to be pre-announced so far: CBR has the word that Jimmy Palmiotti and Amanda Conner will be co-writing a Harley Quinn regular series to start later this year, which given the givens at this point must mean November or December.
Palmiotti: We took a good long look at the New 52 version and then applied it to what we were going to do in the series. Harley is a complex character and we are going to build on her background, motivations and her home and supporting cast. Sort of what we did with Powergirl but with a mix of a bit more homicidal maniac added in.
Conner: That original version is what seems to be stuck in my head, but at the same time, I always thought it would be cool to see Harley (but not her Harleen self) outside of her costume, and what she would be like. That's kinda what we have with this version of her.
