I've never read the books so this is just a non-fan's opinion, but if she's really postponing the book indefinitely only because she's sad it's been leaked then I think she's being a bit overdramatic. I can totally understand how it might make her upset if it was leaked by someone she trusted but then why is she taking it out on the fans? If anything it just seems to have increased anticipation for the book which I'd think would be a good thing? It's sad but with the internet, leaks and spoilers have just become a way of life. I mean, if all movie, tv and music people reacted the way she is when details about a project leaked, we'd never see anything get made.
