Off the top of my head here...
Tyrion- prob dies
, Dany , Jon- at least one dies. Maybe both
Cersei - could see her dead or slithering off to essos
Jamie - dead as dead gets
,Arya, Bran, Sansa - at least 2 live imo,
Gendry - meh. Too close to call
Bronn - probably dead
Mountain - dead
Melisandre - already told us she's dead. I believe her.
Theon - dead as Jaime
Sam - alive
Varys - the route odd Littlefinger. There's no place for him in this new world
Hound,Tormund, Bri, Gilly, Mormont, little girl Mormont, Pod - these are done of the tough calls to me. Lean dead on most.
Davos - alive
Grey Worm - everything screams he should be one of the first to die at winterfell, so I'll say alive.
Meera - probably never see her again, so alive?
Missandi - no clue. All men must die. But we are not men. So... alive.
night king - either Jon kills him or they just figure out a way to get rid of him again. Not sure which. Dead.
one eyed dude that keeps dying - beric is dead imo
.....that's 28. Are we really going to have 20+ of them survive till the end of the show?
