I think either Magnagall or Lupin will die off. I want to say Dumbledore but Harry needs a mentor to fight Voldermort. At the same time, maybe Lupin will become his mentor. I'm really annoyed that Sirius had to die in the last one. I'm still in mourning!

Ron--for the personal impact to Harry,shock value to the readers, and (theory) it would make him and Herimone much closer without Ron's jealousy factor.

It can't be harry, ron, hermione or dumbledore. It could be either lupin or hagrid. But i'm leaning toward lupin cause he's the only good one left out of james' crowd. This will give harry more of a reason to avenge all these death and give him moreo courage to fight voldemort. Theory ofcourse. I don't want either of them to die :(
