She-Hulk currently has no series in the works, and Spider-Girl got cancelled and is currently being shunted around various Spider-Man anthology books. Books that don't sell get cancelled, and Marvel's pretty darn good about giving them lots of chances. AF hasn't sold well in a very, very long time. As much as I love them, they probably wouldn't now, either.
(That's not to say I don't think it'd kill them to come out with a AF or OF miniseries, because seriously. The last one DID do well enough to warrant THAT much.)
