I haven't said my feelings towards the date change, so let me get out of the way: I like the idea that it was changed from Christmas 2012 to Summer 2013. Because everybody wants this film to work so bad, this gives them enough time to make it good. And since this is a Nolan-Synder film, with action being the keyword; summer seems better. Plus, the last time this happened to a film that was reboot (of sorts) that was suppose to be out during the Christmas holiday but was pushed to the summer, and that push back must've helped the final product, was JJ Abrams' Star Trek.
However, MOS being released a week before a Disney film, in this Monsters University which is a prequel to Monsters, Inc., has got me a bit worried a little as kids movies overtake other films regardless of that film's BO or reviews, etc.
