Aliminator, the reason the trailers and teasers dont' have guts or blood in them is because those are edited for all audiences. That's what the green thing at the beginning of the trailers are for. Basically they do it that way so that no matter where they are projected, the scenes and images won't offend anyone. Now, the movie itself shouldn't have any need to hide anything so that's when they actually show the gore and all that. Now, I myself personally don't care about the rating. I've seen the trailer, I've seen the teasers, I've seen the featurettes. I myself think this movie is going to be awesome and I'm not going to let something as little as a rating ruin it for me.
