rand will die on the slopes of SG, at the point of the bore into the land of death...they have already stated that the body as just that is easy to maintain (remember moiraines words to rand in the stone) but to what end with no soul to put in it? nyneave should be easily(sort of and with help) able, though quite uniquely, to rip from the DO's grasp rand's soul. she has already figured out how to break his clutches on the bodies of the male channelers. nyneave must live to prevent the breaking of the world from being a total repeat of the previous breaking..madmen with the power shall need to be made sane. and it would give her the opportunity she needs to cure rand of madness as well. kind of a 'here hold this weave' so she can clear the taint then take back rands soul and place it back in his body. once the bore is closed again the gates of death are once more sealed.
