Hobbit Release Soon!

With only one week until The Hobbit is officially released, there are a few questions that are left unanswered. For one, how is Peter Jackson going to be able to split a 270 page book into a three part movie? By looking at the trailer, it shows up to the part where they are captured by the goblins (1:10 into the trailer), which is well over 100 pages into the book. My theory is that many things will be added to the story did not occur in the book, especially towards the end of the story.

I want to hear what you think they are going to do.
