Has there been any speculation about the blurb of information JK put 
on her site referring to the title of book 7? 

She wrote:

Never give up, you lot, do you? I suppose you think that one of 
these days I'll crack under the pressure and let slip that book 
seven is going to be called - wow, I nearly gave it away then.

It's just that I had the image of leaky cauldrons zooming at my head 
from out of nowhere upon reading that passage. Not that I think book 
seven would be called Harry Potter and the Leaky Cauldron or Harry 
Potter and the Pressure Cooker of Doom or Harry Potter and That Old 
Cracked Pot or anything, it's just that I feel she intentially 
planted some clues in there. Darnit, if we just knew where to cook, 
I mean look.
