I think they, Fox and the MPAA, probably have an understanding about what it takes to make this film PG-13, so they could still be working on stuff that wouldn't effect the rating. It seems incredibly late though; like someone else said, how are they gonna get the reels to the theaters? I don't know anything about that though so who knows. I'm also surprised that they didn't have at least a near finished film for the premiere that they could have shown; its bad publicity - they must be making major changes.
