I don't know if there is anything that has suggested there is going to be some sort of twist or suprise. J.J. always keeps his stuff pretty secretive. There may not be any big surprise, and he is just trying to keep the storyline from getting out.
If the current spoilers are accurate, I feel like they will ruin the film as much after the movie is seen as they will before seeing the movie. They are really godawful and stupid.
