I think most, if not all, in the crypts die. I don't see Tyrion being there though. I see him being out of the crypt and surviving.
I think Theon and the Ironborn die protecting Bran, who survives, as for men to survive long term, the history of men and Children, must survive.
Trying to figure out who will die, I am looking at, men winning eventually and Dany and Jon taking the throne together, breaking the wheel of only one ruler. Both will rule.
So I got Samwell Tarley taking over Warden of the South with the Tyrells and Martells gone and Sam as the lone male survivor of the Tarleys.
Jamie becomes Warden of the West as last surviving member of the Lannisters. I think Tyrion dies killing Cersei.
Gendry takes over as head of the Baratheon family with Arya as his wife.
Sansa becomes Warden of the North.
Yara ends up ruling the Iron Isles as Euron's fleet is destroyed by dragons.
Lots of the supporting characters are going to die. Lots.
