I agree with you on a few, and really disagree with you on a few.
I really really don't think Harry would die. I don't think Rowling is writing books with a lot of warm fuzzies and happy endings, but I don't think she'd kill off the title character at any point.
I definately agree with you about Hermione, but disagree about Ron. I think it is obvious they will end up together.
*wipes a tear from my eye* Dumbledore is almost for sure going to die.
I am going to be TICKED OFF if Voldy lives at the end of the seventh book.
The Weasleys: agreed about Molly and Arthur, and most likely the twins, Bill and Charlie. I almost disagree about Ginny. I think she'll be more in danger of being the bait.
Neville: well, I do think he'll live. I do think he'll discover the truth about his parents. However, the prophesy and the events that happened after the prophesy meant that Neville won't be the one to kill Voldemort.
Cho: nope. I don't like her character, really never did, and she won't be missed if she does die. But Harry's over her, I think. I think there's lots of evidence that Harry and Ginny will eventually wind up together, so if anyone is bait, it would be her.
