Well, Tom Riddle, is
Voldemort. It's like voldemorts shell.....Tom Riddle, isn't completley Voldemort, but, he is part of him. But yes I agree. It would be just like an auther to say that. But that doesn't mean that that is what is going to happen.
Their are clues in the second book;Harry Potter and the Chamber Of Secrets.
It is probably going to be someone completley unexpected. Somene J K Rowling would have thought that none of her fans would have guessed of. Someone like a family member from the dursleys. Nevil, many people think it is him but;
He choose you Harry. Not the pure blood[which acording to himwas the only type of wizad worth being] but you, trhe half blood like himself.
That isn't the exact
quote, but it's close enough. So, it can;t be Nevil, because it is the Half Blood Prince, and nevil is 'pure blood'. Malfoy is pure blood too.
I thought it would be sean finigan, I am pretty sure he is half blood.
Seamus Finnegan is a half-blood. But she also said that she also named Chamber Of Secrets "Harry Potter And The Half Blood Prince". The books are always named for something that takes a fairly vital roll in them:
The Philosoper's/Sorcerer's Stone (Harry saved it from Voldemort). The
Chamber Of Secrets (Harry went into it and met Tom Riddle). The
Prisoner Of Azkaban (Harry things the PoA is responsible for his parent's death and now whats to kill him)
The Goblet Of Fire (It spewed out his name, which is why he participated in the tournement, which helped Voldemort to be reborn)
The Order Of The Pheonix (Society created to help protect Harry/The world from Voldemort)
The last two are kind of minor, GoF could have been called "Harry Potter and the Tri-Wizard Tournement" you could get more specific with events that actually occured in that graveyard, but they might give away too much.
OotP could have been called "Harry Potter and the Department of Mysterys" or better yet "Harry Potter and the Lost Prophesy".
My point? Whoever the HBP is, it's someone worthy enough of having Book 2 named after them. Granted she said she removed stuff from Book 2, and when she did, she decided to change the title. If the HPB was anyone but
Tom Riddle, she would have had to have taken quite a bit out of book 2.
But still. Like I said, it would be someone totaly enexpected, she probably knew that everyone would expect Tom.... Seneus finigan, no-one pays much attention tot eh side chars normaly, so it would not be a big shock to me if her turened ou to be the HBP.
Don't forget that Hagrid played a big part in Book 2 as well. Wasn't Collin Creevy in Book 2? Does anyone remember if he is a half-blood or not? I thought it was mentioned somewhere that he had good potential or strong powers or something (that he might not realize), just as a sidenote somewhere or something.
Hagrid, is also a good possibiliyty for the HBP, although, he would be movre of a HBK....
