Most of what I posted has been foreshadowed - what has not been foreshadowed, I got wrong.
Kings Landing - Yes, I knew that Tommen would take a nose dive out the window, but we all knew Tommen would die early to fulfill Cersei's prophecy so, predicting his death was not going out on a limb. The wild fire has been foreshadowed all season, and really all series. Cersei has frequently mentioned burning cities to ground, Jamie mentioned it earlier this season, Bran's vision, Cersei losing the ace up her sleeve with the Mountain - all pointed to her blowing stuff up. I actually expected the damage to be more wide spread - to fulfill Daenerys vision when she walks into the throne room and it looks torched. I will predict now - that when she sacks Kings Landing it will be devastating - so that when she gets the throne, the city will be in ruins.
Dorne - Dorne was the obvious choice of Westeros ally for Daenerys - none of the major houses made sense. Dorne hates the Lannisters, and we already knew they were in the show. Vale - occupied up north, and Varys hates and distrusts Littlefinger. Varys would know the Tullys were evicted. Northern Houses were in disarray. Boltons and Freys were allied with Lannisters. Lady Olena - she has been a TV favorite character, and they made the point to get her out of Kings Landing - she seemed to be positioned to have a role going forward, and Tyrells have an established army - the fewer armies Daenerys has to face, the better - so an alliance of sorts made sense.
Freys - I got this mostly wrong. It seemed fairly obvious that Arya would kill Frey - her Bravos story was done, she really has no other role/motivation other than revenge in the show. I did assume the damage would be more widespread based on the previews showing the Freys and Lannisters together. I thought Arya would poison Walder, and then chaos would ensue as the two sides blamed each other.
White Ravens - this was a book thing - the show is beyond the books, but the title of the show was the Winds of Winter - white ravens are used to signify the start of the long winter. Seemed likely that Winter is no longer coming.
Sam/Gilly - seemed like there would be some payoff for his journey south other than simply stealing his family sword. Reaching the Citadel was likely.
Winterfell - "Queen of the North" does not have the same ring as "King of the North" We saw Littlefinger and Sansa talking - and we knew Littlefinger has always been obsessed with her. I did think maybe he wanted to stay in power behind the scenes - hence the marriage to Robyn as a twist, but the show made it quite clear that his only goal is the Iron Throne. We saw Davos confront Melisandre - I guessed wrong on how that woudl play out - I thought Jon would side with Melisandre for the reasons she cited, and that Davos would be the one to leave.
I whiffed on Brienne and Pod meeting up with Brotherhood and Hound, and seeing Euron leave the Iron Islands. I do think before Daenerys heads to Kings Landing, she will have to deal with Euron's fleet - again, not really going on a limb here.
