D23 is today and they just announced two big Pixar films.

The first one, to be directed by Bob Peterson (co-director of Up) and produced by John Walker, will be about dinosaurs. The movie, which does not have a title yet, asks the question - what if that life-changing asteroid missed Earth? The hilarious tale depicts a world where dinosaurs never went extinct. The movie is scheduled for November 27, 2013.

The second project, directed by Pete Docter (Up) and produced by Jonas Rivera, is about going inside your mind. That's all that was revealed, but it's coming May 30, 2014.
They also have Brave coming out next summer and Monsters University (the prequel to Monster's Inc.) come out summer 2013.

They also announced a new Tangled project.
