I DON'T think Bella will have a baby named Nessie, and I don't think they will live in a cottage outside the Cullen house. The Cullens have to move on sometime.
I am positive that Bella becomes a vampire, and marries Edward. i think Team Jacob is gone for good now. There is no chance that Jacob and Bella will be together, But I think, in the corner of my mind, that there is tiny, minuscule chance that Jacob imprints on Tanya. At the very least he will imprint on some one.
I think Sam will be able ot stop being a werewolf soon. I think Charlie will hook up with Sue Clearwater, and Leah will find some one else, and gte over Sam. Jacob will be chief.
And everything will be good.
