Its a load pf rubbish if perople pretend to know about the book before pr an hour after the book is released... It's impossible to have done it think about it!
I guess people think it's funny to try and leak stuff.... (like the time someone hung dumbledores name over a bridge on a high way just before the book was released... We ALL new what that was about.
Sometimes things generally do leak... but i wouldn't believe rumors unless i read them for myself on stephanie mayer . comn
