So the Disney Pixar twitter account
just announced their next movies for 2014 and 2015, and they sound suspiciously familiar:
Just announced: Director @leeunkrich and producer Darla Anderson making a film that delves into the vibrant holiday of Día de los Muertos.
Pete Docter's next film is going to take you to a place you know, but you've never seen: the human mind. It will release June 19, 2015
