Wow…hold your horses hehe…I’m one of those people who read the books only once and if I remember correctly I read Breaking Dawn back in August (or was it July when it came out?) 9th 2008 (was it?)…so yeah it’s more of a question of what I remember from the book hehe But I like it that way too…the films seem more fresh and I’m actually curious of what happens not only checking if they got it right, you know? ;) 
So lets see…since it was not my favorite book from the series, I guess I won’t be mad, if they changed a few bits in the end…the ‘battle’ was just…a disappointment…so any changes there will be welcome* I have always been curious about the scene where Bella goes alone as a vamp to see Jenks* I think that is one of the key scenes where she is ‘grown up/dead’ and handles things herself also being confident and strong, you know? Of course, the whole Renesme business is puzzling me* But mainly I guess I just don’t want the film to be too cheesy or have too many of those cheesy Emmett-one-liners…but I guess that’s inevitable hehe
