It was fun... And I also got the HBP right and who would die. (No choice really on who would die - standard hero fare on who dies and why....)

I'm afraid that it will make the final book fairly predictable, but JK may surprise us.

Some of my predictions:

The HBP was acting under Dumbledore's orders right up to and including what happened at the end. He will turn out to be a good guy and will save Harry right before he snuffs it in the final book. (The HBP was in love with Lilly Evans - she was the only friend he had - and her death was devistating, even if he didn't like James P.)

Several options on who RAB will be and what Wormtail still has to do. (Wormtail and Harry are not done - based on Dumbledore's statement to that affect in Prisoner.) Probably RAB will be Regulas Black. I am hoping for Ludo Bagman's Father. (One of the Death Eaters was his friend.)

Harry ends up as DADA teacher (if we get that far)

Hermione ends up as transfiguration teacher, as McGonagal is now headmistress.

Ron either pleys Quiddich or goes into the Minstistry.

Draco ends up being an OK person. The next generation of the HBP - not enough courage to stand up to the Dark Lord, but not really a bad person in his own right.

Arthur W. becomes minister of M.

There is something hidden in the Room of Requirement that will prove to be important. (And it is why there has been a curse on the DADA position)

Stan Shunpike is released from prison and goes back to his job on the Knight Bus, or takes over for Ernie who retires.

Victor Krum still has some roll to play... but I can't guess what.

Harry ends up on Chocolate Frog card.

Other stuff that should happen, but probably won't:

Harry publishes a new version of the potions text dedicated to the memory of the Half Blood Prince - with all the corrected versions of the potions.

Hagrid and Madam Maxine get married. (not sure where they would live - Hagrid won't want to leave his brother)

Neville and Luna get together.

Percy finally goes home to his family

Hermione invents a potion that cures the werewolves.

George (or is it Fred) marries Angelina.

Hermione and S.P.E.W. make some progress and even secure the goblins some addtional rights.

Vernon, Petunia and Dudley are attacked directly and end up owing their lives to Harry and magic.

Oh, I definitely see Neville and Luna together.

I'm not sure we'll get far enough to see who ends up teaching what at Hogwarts. However, I'm not sure how she can possibly wrap all the subplots up with just one more volume: I just can't see it happening in less than two.
