I don't think Harry will die, he is the most important one! He has to kill Voldemort, and Snape perhaps.. ..but nope, Harry can't die! If one of the main characters have to die, I think it should be that blonde boy, I don't know his name, because, he is considered as one of the main characters, isn't he?
"In June 2006, Rowling, on an appearance on the British talk show Richard & Judy, announced that the chapter had been modified as one character "got a reprieve" and two others who previously survived the story had in fact been killed. She also said she could see the logic in killing off Harry in order to stop other writers from writing books about Harry's life after Hogwarts."
