Edward isn't going to be overused in this one, or so the new director (the one who did The Golden Compass) says. There's going to be half of Twilight Jacob and then the transformed Jacob. I'm quite looking forward to his friendship with Bella because they had a good time in the book. But then I noticed on one of the featurettes on IMDB that Edward and Jacob appeared to be getting ready to fight. It doesn't happen in the book, but it's intriguing nonetheless.
