The book does not go on sale until the 27th. I'm sure that ppl (if there actually are any, not sure of this) have been provided with advance copies they've also agreed to some sort of NDA. I dislike the thought of RAFO promoting that.
Besides, I think it will promote all kinds of faux nonesense. "Rand is a transvestite!" "Egwene kills Gawyn in a fit of rage!" etc etc. I don't think we need that either.
