Deathly Hallows Predictions

Avert your eyes if you must, but I am putting my predictions about the seventh Harry Potter book here, on the internet, before the book is released, so that when some of this stuff actually comes true, I have it on record that I saw it coming.

1. Percy Weasley will betray his family, friends, and even the ministry; in his ambitious pursuit of power, he will become a spy for Voldemort, who after all is a very powerful dark wizard.
   
2. Ginny Weasley will be an Animagus, and will transform into a cat of some kind. She will also be proven to be one of the most powerful witches (meaning the strength of her magic, not authority) of the age, and certainly the most powerful of the Weasley clan.
   
3. Peter Pettigrew, a.k.a. Wormtail, will betray Voldemort in an attempt to repay the life debt he owes Harry.
   
4. The Blacks will turn out to be descended from Slytherin himself.
   
5. Harry Potter will destroy all the remaining Horcruxes. He will find the Slytherin locket among the Black heirlooms.
6. Harry and Ginny will get back together at least one last time.
   
7. Harry will die to save other people. In doing so, he will leave the same magical love protection on others that his mother left on him.
   
8. The famous prophecy, which states "neither can live while the other survives," will be proven to have a different meaning than previously understood. Clearly both of them are already alive and surviving at the same time, so the prophecy must have another interpretation. (This goes back to my previous belief that the prophecy was no longer worth guarding once Voldemort had already succeeded in fulfilling it by "marking" Harry "as his equal" and making the transfer of power. Voldemort already wanted to kill Harry Potter, and Harry already wanted to kill Voldemort. Dumbledore knew all of this, and yet he still put all those lives at risk guarding useless information? No, there would have to be something else to the prophecy for it to have been worth the trouble the Order went to to guard it.)
9. Someone else will have a scar upon them from surviving the Killing Curse.
10. Hagrid's brother Grawp will come into play as an essential part of bring the rest of the giants over to the good guys.
11. Somebody will knock boots. It will not be described, because Scholastic is still marketing this as a children's book. But someone is going to get some.
12. We will find out what is behind the veil in the Department of Mysteries.
13. Bellatrix Lestrange will die. Personally, I hope it's at the hands of either Neville Longbottom or the Dark Lord himself. Either would satisfy my sense of poetic justice.
