Yeah, I anticipate some sort of tragic sacrifice on Harry's part in order to stop Voldemort.
Yeah I think that because they are so linked (same phoenix hair in their wands, Harry's scare burning when Voldemort is near, Harry actually being able to hear Voldemort's thoughts, they are both parseltongued, etc). Every book they get more and more connected, and every book gets darker and darker. I am thinking that Harry will possibly die in this one.
