I really don't care who dies. I just hate it when authors leave loose ends. So dead characters are better than unanswered questions.
As long as she doesn't kill off characters to avoid answering questions.

I would be very surprised, given Dumbledore's association with the Phoenix if he didn't come back in the last book. His unshakable confidence in Snape leads me to believe that he deliberately stalled Draco until Snape appeared on the scene to "kill" him. And if Dumbledore can come back, why not Harry? Harry may indeed be a horcrux, but perhaps a dip in the dirt can purge him of that.
