Ok honestly I didn't have a doubt that they wouldn't get married. I mean come on... and obviously Stephenie Meyer thought the same (that it wouldn't be a surprise to readers) or else she wouldn't have given up that peice of information. Although i still do expect something to happen during the wedding. or shortly after the wedding. And I bet anything that if Jacob is not THERE at the wedding he will be close by watching. There's no way he could stay away from bella.
But maybe that's just me. : )
