I'm pretty sure I read somewhere how JK said she would continue writing after book VII, but she said she probably wouldn't write about Harry's life after school -- thus implying that he will HAVE a life, that is, not be dead! I can't believe she would kill him, readers would go nuts. And poor little children, and poor little me, would cry and cry
! I think good will conquer evil, it would be really stupid to just kill Harry and then be like, mwah-hah-hah, LV will now proceed to terrorize the rest of the world! Anyway, the book is told from Harry's P.o.V., so it would be weird to suddenly switch to, say, Hermione's perspective and have her crying over Harry's body...
. I think the only way Harry will die is if he and Voldemort both die fighting one another.
