I love spoilers as much as the next person, but Friki annoys the hell out of me, always had. It’s a mix of sense of entitlement and personality cult, you know what I mean?
And, as far as spoilers and speculations go...
BoW: Beric, Gendry, Eddie, Jorah, Pod, Greyworm, Theon, and Tormund or Brienne. YET, it lacks a major character, doesn’t it? It has to be a Stark, there is no way all four Starks - yes I’m putting Jon in the Stark column - survive.
Someone asked it there’s a river near WF, I don’t remember if there was one in the books, but Sansa and Theon walked right next one when they ran from Ramsay trying to reach the Wall. Maybe the same river runs South. Also they mentioned more than once that the cripts have some tunnels to the outside so, yes, I can see how a lot of characters who one would think have very little chance of surviving, like Gilly, Little Sam, and even Lyanna Mormont, will not die.
As for Bronn, I believe he saves Tyrion’s life, which will make people think Cersei sent him to save her brother - another proof of Tyrion’s traison.
Assuming the spoilers about Tyrion’s are true, I can envision a scenario where he realizes that for Jon or Dany to rule - and I think it is one or another - there shall be no more Lannisters (like there shouldn’t have more Targaryens) and there shall be no doubts that the king or queen will not tolerate anyone who tries to disrupt “peace”. So, I can see Tyrion lying and confessing things he didn’t to make sure the ruler he chose - again, it’s either Jon or Dany - will reign. Kinda of the opposite of his trial when Joffrey died. It would be a bittersweet ending for the character, devastating for the fans and a George thing to do.
ETA: I’m on team “Jamie kills Cersei and dies with her”. They were born together, they will die together. Maybe she hurts him fatally and then he kills her. Think Marcus Aurelius and Cleopatra, something like that.
ETA1: Sansa re: if she survives, and if Jon or Daenerys (or both) ends ruling, I can see D&D making her Hand.
