It looks like it's going to be fairly true to the book, but also include parts of the story that aren't in the book (because Tolkien wrote about them after he wrote "The Hobbit").

It's also going to be 3 films to cover that additional content, so it looks like it's going to be very detailed. Peter Jackson is directing (He directed the Lord of the Rings trilogy), so all in all it's going to be fantastic (I hope)
