Harry and Voldemort will die. Why? Voldemort put a part of his soul in Harry, and to Kill Voldemort, Harry will have to kill himself. Pluse, I read an article in the newspaper saying that they must die so that no Author will try to revive the Potter books when Rowling is gone. If you disagree, tell me why.
Really, does it take that much effort to type like a human? 😬
Also, this has been said many times, in many of the many Speculation threads already posted.
