Yes, my obsession is great with Harry. I love these books. LOVE them. As a distraction, I've been rereading books five and six in preparation for the last. So lets play....here are my predictions.
Dumbledore will not be coming back. No matter, how much I wish he would. JKR clearly stated he would not be - I went to her book reading last summer in NY. However, I am afraid that the fact he was the secret keeper for Grimauld place could be a significant problem.
Dumbledore's brother, I think will become relevant.
Harry will win in the end thru LOVE. However I am not a 100% certain how it will play out or if he will end up using an unforgivable curse. However, aren't they in war? And wouldn't it be forgivable in that context?
I think there is a very good reason that the boy wizard has made friends with a Hippogrif, a Dragon, a Giant, a Centauran, flying motorbike, two way mirror, Dolby, etc. I think they will all come into play somehow.
RAB, I am not sure. Did they ever find his body? I think his significance ended with the hortecreux.
Aunt Petunia will divulge her link to the magical world, but she herself is not magical. And he link may lend itself to Lilly's eyes. Which I also think have some significance, more than Harry’s are in their likeness.
Lastly, I am not sure about Snape if he is good or bad. But that is the beauty of Snape, because he is both I suspect just like the rest of us.
Umbridge and Rita Skeeter will both return.
I think that Wormtail will help Harry in some way in the end. And that Voldemort can’t kill Harry because of his blood being part of his reincarnation.
Connection to Godric Gryffindor to Godric Hollow and to one of the Potters. All of the pure blood wizards – James – are somehow related to each other.
Potter was on the Black family tree, however Dumbledore was not. Could Dumbledore be related to Lily and Petunia? We don’t know Dumbledore’s lineage, could he be born of Muggles?
As you can probably tell, I love Potter. Please, do share your predictions....but once the book received, don't spoil it for me. Personally, I will be posting about it, but giving everyone fair warning.
