Nice job copy-pasting from mugglenet. =P

Yeah, I'm stoked. As far as deaths go, Rowling said something about true evil attacking people that matter most, and when she told her husband who was going to die, his reply was something like "Oh no! Not that one!" As long as Harry, Ron, Hermione, and Ginny make it through, I'll be fine.

I, too, think Hagrid is a likely candidate. Hagrid's entire life was built on Dumbledore's support. Without Dumbledore to constantly vouch for him, to provide him with a job, a home... well, I just don't think Hagrid has a whole lot going for him if Dumbledore isn't there to back him up. I've always felt that Wormtail was going to die in the end, and given Sirius's death, I imagine Lupin dying is a very real possibility.

Also, Rowling has said that one character got a reprieve from death and another died in that character's place. If this is true, I imagine that means those deaths do not significantly alter the final outcome. She's had this story in her head for years, and I doubt she'd decide to make such a major change as deciding not to kill someone incredibly important (or deciding to kill another important character in his/her place.

Apparently, questioning Dumbledore's past is a "profitable line of inquiry." As such, I believe it is very likely that Aberforth will be making his long-delayed appearance, or rather, he'll be officially announced. I think it's been made abundantly clear that the barman at the Hog's Head is Aberforth Dumbledore. Harry first goes there after seeing a picture of the old Order of the Phoenix, in which he sees Aberforth for the first time, and at the bar its noted that the barman looks familiar. Also, in book four, Dumbledore mentions that his brother performed illegal charms on a goat. The Hog's Head is explicitly described to be smelling of goats. It's also noted that the barman was at Dumbledore's funeral, which wouldn't have deserved mention if he wasn't important. Rowling has also said that we have yet to officially meet her favorite Order member. The only one we know about who has yet to be properly introduced to the story is Aberforth.

If Dumbledore's past is going to become important, who would know it better than his own brother? Also, one must remember that it's possible that Aberforth has a good idea about the prophesy. Trelawny's account of the night of her interview reveals that it took place at the Hogs Head and the one who caught Snape outside of the room was the barman.

I'm particularly interested in the significance of the two-way mirror. If it's making a return, does that mean Sirius is on the other side? Rowling never hesitated to confirm that Dumbledore was dead and gone, but she's always been a little sketchy on the details of Sirius's death. She's always insisted that it was absolutely necessary that Sirius die, and I really doubt that eliminating father figures in Harry's life was the only reason.

Other things I'm curious about:
How does Harry find Godric's Hollow? A proper explanation of the fidelius charm has not been given, but the only people who should know of the location are Wormtail, the secret-keeper, and Voldemort. If the charm is still in place, does this mean Wormtail will tell Harry where it is as part of his life debt? If not, how will Wormtail fulfill his life debt to Harry?

It was recently announced that when the screenplay for Order of the Phoenix was being written, Rowling said explicitly that it was a bad idea to leave out Kreacher. This lends credibility to the theory that R.A.B. is Regelus Black and that Kreacher was the one who accompanied him.

Given that Rowling has frequently insisted that the power of love is what will allow Harry to defeat Voldemort, I imagine that means most characters will get a happy ending, at least the ones most important to Harry (Ron, Hermione, and Ginny). I don't think she can so easily tear people Harry loves the most. It wouldn't do much to help him use that power against Voldemort.

That's only the surface of what's going through my mind. This post is long enough, though.
