I'm guessing JKR is going to eventually explain e-v-e-r-y-t-h-i-n-g, down to the last cobweb in the attic of Hogwarts.

Treebeard commented that she is in danger of going "Frank Herbert" with comments like this one that she made during her live web chat on Bloomsbury's website:

Tess: What muggle song do you imagine would be played at dumbledores funeral
J.K. Rowling: Surely 'I did it my way' by Frank Sinatra.

Oh, surely not.
