Ugh... I really didn’t want to think of anybody else dying except Voldemort (or course) and Snape making the ultimate sacrifice to show all that he was a good guy.
For maximum impact (if thats what JKR is going for) its one of the five (Ron, Hermione, Ginny, Neville, or Draco).
I can’t see it being Hagrid, but I can see it being one of the “kids”.
(Counting the hours.... Amazon please don’t be late....)
If you don't want clues to what is going to happen stay away from it.
They are talking about over half a dozen of the characters dying.
