While I am sure that Voldermort will die, I agree with Zonko that he might not be the one who kills him, how ever I also want to put it out their that I do not think harry will die because in an interview with JKR she was asked if she could speak to Harry what would she say, and she said" I would apologize for all troubles i am put him thru" and since she has already written the end of book 7 that says to me that she is did not kill him; the way she said it gives hope the future, you have to read between the lines with her <_< <_<
