I think that at some point Pettigrew is going to get strangled by his silver hand. Maybe in a moment of wavering when he considers betraying Voldemort?
Yeah. I think the whole “Stephen King/John Irving begging JKR not to kill Harry off” thing was engineered in advance. JKR isn’t wealthier than the Queen by accident.
I think Ginny gets it, though, in spite of Harry’s best (if chiche) efforts at the end of Book Six to shelter her.
And maybe Neville.
And Ron. So Harry ends up with Hermione. 
Nah, advice from the other side is too close to “coming back”. I do think, though, that Nick will end up resolving himself to walk through the curtain, and finally take his place (whatever that might be) in the Beyond.
Does that count as a death prediction? I mean, that’s really Nick’s happy ending, not a sad one at all.
My picks, in order of likelihood to die:
Peter Pettigrew 6:5
Percy 7:5
Bill 3:2
Neville Longbottom 12:7
Hermione 2:1
Charlie 3:1
Nymphadora Tonks 5:1
Ron 5:1
Remus Lupin 7:1
Arthur Weasley 15:1
Fred 10:1
George 10:1
Ginny 40:1
Rubeus Hagrid 40:1
Severus Snape 50:1
Draco Malfoy 100:1
Minerva McGonagall 100:1
Molly Weasley 150:1
Harry 200:1
Obviously Voldemort is a dead certainty. No bets will be taken on that. I think that as many couples as possible will be broken up by the end of the book. That means either Hermione or Ron, Remus or Tonks, Fred or George. The idea that Fred or George will die is a great one. I hadn’t considered it before, but it would be a very powerful scene, in which the surviving twin has to face living alone.
I also think that the faculty are going to survive, if only because Hogwarts has to survive, perhaps moreso than Harry does.
This is my new favorite way for Voldy to kick it.
This is really my least favorite theory regarding the final book. It would be quite foolish for someone to preserve a piece of their soul to prevent their own death in something living that is not under their watch. What if book one opened with the Dursleys and Harry getting into a giant car crash on the way to the zoo and all died (obviously, this would make for a much different series of books, but you get my point).
My money’s on Ron, Snape, and Neville as the deaths that cause the biggest reactions. Not Harry (although for as long as I remember, JKR has fielded the question of a book about grown-up Harry with “How do you know he survives?”, so the kiddies have been warned).
I had the same idea about Lupin, but JKR has specifically shot down the idea that Pettigrew will kill Lupin with his silver hand. I still have a hard time imagining Lupin getting a happy ending, however. He just has an “air of tragedy” around him. I can imagine him getting killed by Fenrir pretty easily, probably while protecting Harry.
As soon as Pettigrew got his silver hand, I was sure that Lupin was for the chop, but given that Lupin’s now found love with Tonks, I’m going for a reversal of the legend. Or Pettigrew might kill Fenrir.
Yes, it is really stupid, which is why Voldemort would never try to do such a thing. The point is, though, it could well have happened accidentally, without Voldemort necessarily even realizing it had happened, and certainly without him intending it.
