Well, Ive read the spoilers and most of them Ive forgotten. I refuse to reread the spoilers again... but I will say this
I am an artist and musician for a living. Seeing as the 4Chan spoilers were based on a screening back in Oct, I bet that by the time the film is released, quite a few things will change. When I start an idea for a song, for the most part, by the time the track is finalized... its gone thru a few hundred changes and will bear SOME resemblance to the initial idea or concept, but winds up being a finished product that is streamlined, listenable and is a completed piece.
Basically, from such an early screening and cut of the film... Im sure the cut we will all wind up seeing in the theaters will still have a FEW of the listed spoilers in it, but count on it being a very different product altogether!
