Or were in his future back in EOTW, but it could well be fulfilled.

IRRC, Min only had two viewings related to Lan (one of him, one of Nynaeve). There was baby with a sword in front and the ruined seven towers (which could be fulfilled or not, we'll know only after reading AMOL if it referred to something specific or to the raising of the Golden Crane in KOD), and there was Lan's ring that Min told Nynaeve was related to troubles but in the distant future. The one of Nynaeve is almost certainly fulfilled. The ring was how she got Lan an army. As for troubles, he's riding to fight TG....

A more recent viewing of Nynaeve has her kneeling in front of a corpse, in grief. Rand? Lan? Someone else? We'll see. The timing makes it just as likely that it is Rand as Lan. It could be about Rand, though there have been many already about him in a funeral bier (the first one where Nynaeve is involved, though - and we can't tell if it is contradictory (it's not Rand) or complementary (it provides the first evidence Nyaneve may be involved with the "is dead but lives" part, even though I still think this goes massively against certain themes in the series) to the all "three in a boat" variants, or Egwene's dream of a man on a narrow cot who is not dead yet and musn't die, but outside his funeral pyre is being built and some are mourning and others are cheering.). If it is about Lan, I guess it was intended that we more readily associated it with Rand's death.

After so many months near Nynaeve/Lan, and knowing Nynaeve's worries now that he's gone, Min normally would have come forward to reassure her if she saw anything hinting at happy events in their future. She must not have seen any children for the couple yet, for instance. Nynaeve's not pregnant, any such viewing would mean Lan and Nynaeve would be reunited. It doesn' sound like Min has seen anything with which she could alleviate Nynaeve's worries or give her some hope.

There are quite a few characters we know can't die, or at least very soon. Mat-Perrin-Rand-Egwene-Elayne all have a few prophecies about them still to be fulfilled. It's far less clear with Nynaeve-Lan, though it seems likely Nynaeve survives either Rand or Lan or both.
