SPOILERS for those who don't want to know, but apparently the most recent issue of Entertainment Weekly reveals the "split point" for the Deathly Hallows movies. You can read the excerpt HERE, if you'd like to know.
Without giving away what the article says - I have to agree that it is a lot later into the book than I expected too.
I have been rereading the books in a run up to the movie. I honestly don't remember how far along in the book this point was. Interesting place though with how far along the article says it is. Once I get to the book, I guess I can get a better idea of the content of movie 2.
