I guess so. I don't exactly know the rules about moving release dates, and whether or not you have to stick with it, or how long you have until you can no longer change it. :shrug:
I just find it so weird that Ratatouille will come out in June, yet the trailer is already out. But Pirates, as far as we know, is coming out in May, but still nothing.
They don't even have one of those really teaser trailers, like the one they came out with for Terminator 3 where there were no actual scenes of the movie, but it did reassure you that the movie is coming.
Hopefully, we're going to see it this month.
