I'm afraid you read that headline correctly. Unfortunately, Pixar has decided to release their upcoming prequel to Monsters, Inc., which was recently given the title Monsters University, in the summer of 2013 instead of in the late fall of 2012. After having been changed from November 16, 2012 to November 2, 2012, it will now hit theaters on June 21, 2013. But this is surely for a good reason, as Pixar always does what they think is best. The movie was probably taking a bit longer than usual (the Pixar process usually takes about four to five years) and they didn't want to rush the film, so changing the release date was the only good solution. So you can still expect to see Sulley and Mike back up on that big screen again, just a couple of months later than you were expecting.
