Well, I hope Harry doesn't cop it. I can't honestly think of much kid's literature where the hero dies. And anyway, apparently JK Rowling did a conference thing in New York last summer. She took some questions from the audience and somebody asked her if you could have anyone of your characters to dinner who would it be. She replied, Harry, Hermione and Ron then she said do they have to be alive at the end of the series. The questioner said no so she said in that case Dumbledore and Hagrid!
So what does it mean. I think it could mean the main three are alive at the end and possibly that Hagrid cops it.
Well, all will be revealed soon!
