He certainly worked on 'Brave' (as co-director and the voice of the Raven), so I'm guessing so.
Since he did co-direct Brave, he's still working for Pixar. I have a feeling that he's taking part of the production of Planes(which I can imagine he's probably wishing to pull a Max and go nuts on the people who approved of it).
