How to split the Breaking Dawn?

It's a hard question to everyone as well as not many believe that producers will make it and hot up the release of the last movie.

I think that everyone can agree with Melisa Rosenberg idea to spit the book like into to lives: Bella as human and Bella as vampire.

We can concentrate on this opinion, than the first part of Breaking Dawn should be finished exactly on the moment where Bella has been "born" again. It can look like the part from Resident Evil. I believe the end of the first part is going to be very dramatic and full of emotions with tragedy in the air.
