i think that they will put in the whole lockhart scene because thats when Ron, Hermione, and Harry see Neville and his grandmother and find out about what happened to his parents. Also, that Bode guy gets a Devil Snare when they're there and it ends up killing him. That is one of the keys to this book I think, so I think this scene will be in the movie, although it will probably be more brief. I also agree with the Christmas part. I don't think there will be much of that in the film except maybe when Hermione, Ron, and Ginny talk to Harry about being under the Imperius Curse and all that. I can't wait for the movie to come out, and I really hope it is long!
