Miranda, the AIW release date has been known since last fall, while it was still filming, and hasn't changed. It seems they chose that date purposely and will stick with it unless anything unforeseen happens. From what I've gathered the last few years following some film/box office forums, a lot of times various studios will stake their claims early for the big blockbuster-type films, and then jockey around so that these big films are spread out a little bit. Sometimes they do get moved, but I get the impression there's a lot of politics going on to get a "good" release date. We'll see!
