After just announcing the name and director of that Monsters Inc. sequel (which is actually a prequel), the studio has already pushed it back. Coming Soon reports that Monsters University's release date is now June 21, 2013, unlike November 2, 2012 like originally planned. The film tells the tale of how best friends Sulley (John Goodman) and Mike (Billy Crystal) met during college as they, what we can only assume, were holding each other up to do keg stands.
