My predictions:
Deaths next episode:
Tormund - No reason for him to survive unless they want to tack on him+Brienne love story at the end of the show. Seem unnecessary.
Jaime - His arc seems about complete. Although having him kill Cersei would be a big final payoff, I am doubtful he'll be the one to do it. So now seems the best time to kill him. Jaime needs to die eventually due to all his past crimes. You could have Daeny do it eventually for more effect perhaps. Would really be milking it though.
Gendry - Need to get rid of the bastard, and will also remove any last emotion from Arya.
Podrick - He just seems kinda useless now, and Tyrion gave him that full mug when Brienne said just half a cup. He's lucked his way so far, but he's a throwaway character at this point.
Theon - This is his time, defend Winterfell and provide an emotional moment for Sansa.
Davos - He's a strong ally & friend of Jon, which makes me think he needs to die now. Gut both sides of Daeny/Jon so that there can be a quicker / cleaner conclusion in the final episodes.
Jorah - We saw some decent screen time with him, he's done. We had the scene with Lyanna and also his advice to Daeny and receiving the sword from Sam. That's a lot of different moments to make next episode a great time to kill him off. Also Daeny needs to lose some pieces from her team, so he seems logical.
Beric* - This is the moment he's been written for. No point for him to survive. Need to close out the Lord of Light stuff here, maybe he sacrifices himself or has a final payoff with the Night King. He'll die on his terms.
Night King* - linked to Bran's fate.
Bran* - After the wars he'll have no place and he has too much power to survive. "Bran" is already dead, he's reiterated many times he's no longer Bran. He represents the Children of the Forest and will confront their creation. The final conclusion between Bran/Night King needs to be good. Does Bran become the new Night King, or save the current one, or do they "unify" to create something else or do they void each other out? Can Bran warg into the Night King? (the Hodor scene strongly influencing this idea)
Survive (for now):
Team Jon:
Jon - Jon is in it to the end, based on the song/speculation , does he give up his claim to Daeny? I still think he kills Daeny eventually.
Sam - I originally had him in the Kill column, but if he is killed off Jon would really have nobody left (except Sansa/Arya). He needs at least someone on his side and it makes more sense to have a friend that can ground him, like Sam. I still think the crypt ends up a battle zone and maybe Sam can come out a hero (again) protecting Gilly/baby sam. Or maybe Gilly/baby sam are killed, but that sure would be another kick in the nuts. I gotta believe all 3 survive at this point.
Team Daeny:
Daeny - We know she needs to survive at least until the battle for King's Landing.
Tyrion - He needs to survive to record Bran's story, and at this point I'm thinking Tyrion or Arya will kill Cersei.
Greyworm - Daeny needs a "fighter" to remain on her side. Greyworm is needed to command her army.
Missandei - She isn't needed but could have an emotional part to play between her & Daeny if Greyworm dies eventually. If she dies I think Greyworm becomes a much less reliable asset for Daeny.
Team Sansa
Sansa - She's lady of Winterfell and needs to be there for the conflict between Daeny/Jon. We haven't seen the end of "What about the North!?"
Brienne - Needs to survive to be Sansa's fighter, otherwise Sansa has nobody left. (excluding Arya/Jon).
Other:
Arya - I'd be very dissapointed if she dies simply because she really hasn't done much with her list (except for Walder Frey). Top person is Cersei, but also the Mountain, the Hound, Beric - most of these will sort themselves out. So Arya/Tyrion are top contenders to kill Cersei at this point.
The Hound - Needs to survive to face his brother.
Varys - If he does die, it needs to be a way other then by combat, he also seems to have few enemies right now, so possibly survives everything.
