There aren't any female-led ongoing titles in the Top 30 at the moment, but Wonder Woman
are currently outselling Daredevil
, The Incredible Hulk
, The Fantastic Four
, and Captain America
The DC animated line is sticking to Batman, Superman and/or the Justice League because those titles deliver the kind of fast sales their retail partners are looking for. The chances of DC's female characters getting on screen in a starring capacity is actually a lot better in a live action movie or television series where you have the advantage of a big marketing campaign and casting stars to draw attention, while the animated movie line has to generate sales with a very small marketing campaign.
That's not to say it's easy to get them on screen in a live action capacity, as demonstrated by the failed attempts to get a Wonder Woman movie and/or TV series made, but I think we'll see a DC heroine in a live action starring role before we see one in an animated starring role.
