According to leaks, and confirmed by Rowlings, 2 key characters will die and 1 will get a reprieve.
Care to guess who? I am at a loss here, but I am voting for Harry and Voldemort. However, the prophecy did say one must die for the other to live, so that may throw my theis out the window?
Another intersting item to speculate, is Snape a traitor, and to whom? Is he really a Deatheater or a Dumbledore's double agent in Voldemort's camp? Inquiring minds really want to know.
Oh, one last thing, did Dumbledore really die?
