Well I was reading
ixchemala's post about thinking that JK had finished book 6 months ago. That is why we received the title after that whole Pillar of Storge crap. Well I just found a quote that could possibly support that thought/theory. So read and speculate:
“Um ... yes ... you ... you ... see ... see that, but ... um ... if you saw on the Internet, because evil wizards have infiltrated the Internet and have put on there that the title of book 4 is Harry Potter and the Quidditch World Cup, and that's not true. They're just messing with your mind! It's not true at all,...but I'm not gonna tell you the title because I'm a bit superstitious about that; I like to keep it a secret until the book's finished.”

What do you all think. If she is superstitious then the book was finished when the title came out and maybe she was tweaking it. Who knows.
