My brother bought this book and after he read it, he passed it along to me to read. http://www.amazon.com/Mugglenet-Coms-What-Happen-Harry-Potter/dp/1569755833/ref=pd_bbs_sr_1/103-7898131-3983841?ie=UTF8&s=books&qid=1181999868&sr=8-1 It's a great analysis of the story so far and what could happen in book 7. Yeah, I don't think Dumbledore is a Horcrux, anyway. It just doesn't fit in with what he's all about. You change when you split your soul... and Dumbledore didn't fear death. So, I doubt he'd have done that. Although, that's not to say I wouldn't like to see Dumbledore come back. When Rowling said she gave someone a reprieve, I think she meant that she had killed someone in an earlier draft of book 7, but decided later to let them live (but then she killed two additional people). So, Sirius wouldn't have been that because he's already dead. Again, not that I wouldn't like to see it.
