So, JKR revealed that book seven is a blood bath. that more than two characters will die. personally, i think there are lots of options

Voldemort

I think Voldemort will definitely die, as somehow tyhe evil has to be vanquished, or the series cannot end. and she does not want to write more potter immediately after this book. she didn't say she never wants to write it again, she said she might come back to it in ten years time. but to immediately end this series, Voldemort must die.

Ginny

I think very likely, almost certainly. the reason i think this is because she's become such a main character. also, Harry broke up with her to protect her, but i think he knows deep down shes still in danger because everyone knows he has feelings for her. shes still in grave peril whether shes Harry's girlfriend or Harry's Ex.

Ron

The most likely out of the trio i think. We have connected with Ron a lot more than Hermione, and even Harry on some levels. we know a lot about Ron's history and family, which we don't know about Hermione. and to a lot of people, Ron is their favourite character, not Harry or Hermione. these are good reasons to kill him off, but just to make readers cry is stupid and cruel. there will be a reason if he does, and i think he will. i also did a very large essay on the matter, which up until recently, i didn't believe myself, but its becoming more and more appealing.

Harry

i don't think its very likely at all, BUT, my view has changed slightly. in the interview with Ross, she is quoted in saying "In ten years time i may wish to return to THAT WORLD", she didn't say "i may return to Harry", however, that could simply mean Harry's story is over and she pursues another adventure within Hogwarts.

Hermione

I think very unlikely, least likely of the trio. Hermione is the member of the trio most like JKR (Ross interview), and this means she develops a connection with her. plus, as readers we are not as attached to Hermione as we are Ron and Harry. Hermione is almost a sideline character in our minds.

Hagrid

likely in my view, Hagrid has been a father figure to Harry all these years. and father figures seem to be dying at a fast rate. but the one problem with Hagrids death is giants are hard to kill.

Lupin

another father figure to Harry, and with Sirius gone, the closest thing left to Harry that is a reminder of his real father. Lupin is lilely, because of the sub-plot created for him being a werewolf. other than POA, this plot has come to nothing, and it wasn't ammassive thing in POA either, just allowed Pettigrew to escape. Adam is believing a face-off with Fenrir Greyback is possible

Pettigrew

this one depends on decency. if Pettigrew pays Harry back for saving his life in POA, then its almost certain he will die. if he doesn't have the decency, i dont think he'll die. thats the only way i can see him dying.

Snape

likely, because i think he's a good guy really. theres two ways he might die, Harry might kill him (not likely) or Voldemort will kill him for betraying him. i really don't want Snape to die though, so i hope im wrong.

thats all i can think of, give me any ideas you have and ill add them

Ginny's death was also foreshadowed in Chamber of Secrets. I think its likely the red head will finally be executed. There is another foreshadow that at least one Weasley will die - the clock "Mortal Peril." Just some food for thought.
