I think JKR makes that comment, not because Harry is going to die, but to keep the end a mystery. If she let on that he will live, everyone will know the end! well except for all the others who might die, and just how the battle progresses. I think JKR is very brilliant in keeping that comment, it says neither that he will live or die, it keeps all in the relm of possibility. I am not shure, but I believe that JKR said somewhere that Harry's blood in Voldemort will not protect Voldemort from attack or make Harry any more vulnerable than he previously was. Can any of our experts on the interviews find that snippet? Thanks!
