Um, some information from interviews with RJ. I guess it's pretty much open information now among diehard WoT fans (like me), but anyway. Book 11 is called Knife of Dreams, and RJ has explicitly stated that he will end WoT at Book 12, no further. So we can expect either some very thick books, or some very frenetic action in the next two books. Yeah.
