NEW YORK -- J.K. Rowling has kept us waiting for a LONG time.

But finally, with "Harry Potter and the Deathly Hallows" -- the last in her popular series -- there should be some answers to many questions. Here, in no particular order, are some threads that readers would LOVE to see tied up:

• Just who is R.A.B.? Fans already have put forth the theory that R.A.B. is Sirius Black's brother Regulus, thought to be dead. Could he have been in hiding all this time?
• What happened to that Horcrux? And is the Horcrux that strange, unopenable locket Harry and friends found in "Harry Potter and the Order of the Phoenix"?
• What role will Dumbledore play? The dead have made their presence felt in the other books, so what does that mean for Dumbledore?
• What is the deal with Snape? Good guy? Bad guy? Good guy playing bad guy? What?
• What's up with Aunt Petunia, Harry's non-magical aunt?
• Who is going to die? Rowling has said she killed off two major characters. Who will they be?
