If I'm remembering correctly, the soundtrack for the last one was released just as the the movie opened for general release, so it might not be unreasonable to suppose the same will happen this time around.
Exactly. The movie is three months away. The soundtrack (as well as other tie-in merchandise) most likely won't bee seen until around the same time, give or take a week.
I've NEVER heard of a movie soundtrack being released three months ahead of time.
