Looks like this will be Pixar's one shot at a film about a girl because they released the list of the next couple of movies and NONE are about women and NONE are directed by women. 

We've got the Untitled movie That Takes You Inside the Brain in 2015, The Good Dinosaur in 2014, and The Untitled Movie about Dia De Los Muertos.  (This one is produced by Darla K. Anderson)
