New Harry Potter book title released

The new book is going to be called Harry Potter and the Deathly Hallows. It sounds a bit morbid, but what do I know, right? It is the last book of the series, so in a way, it is the death of the Harry Potter books.
On a related, but different topic, what I'm curious about is whether or not Emma Watson will finish the movie series. I had heard a rumor that she was thinking about quitting to go to college. She says that she never intended on becoming an actor and did it just for fun. She says that now she is graduating high school, she wants to go off to college and quit acting. I think it would be a shame to have to finish out the movies with a different person playing Hermione. Just my thoughts.
