Opinions and/or theories on Breaking Dawn?

I do not think any main characters will be killed. I think Jacob will come back to attend the wedding because he knows how much it will mean to Bella. I think at the wedding Jacob will imprint on a vampire, but not one of the Cullens of course. Maybe a vampire in Tanya's coven. I think Edward will take Bella to Switzerland on there honeymoon, and they will finally have . I also think there will be some kind of major fight scene, but I am not sure who it will be with. Oh and I think at the end Bella will finally become a vampire.
