Here are my predictions:
Tyrion betrays Daenerys , he dies
Theon saves Yara, kills euron, however he becomes the ruler of the iron islands
Cersei betrays everyone and turns back, jamie joins jon. I also think he will kill her
The hound fights the mountain and they both die. I think Arya will be involved
Arya will marry Gendry
Jamie will save Brienne, but maybe she will die
Daenerys dies with drogon fighting the night king and viserion, and jon/rhaegal defeats the night king
Jon sits on the throne with davos as the right hand
Thinking exactly the same about Daenerys and Jon.
Eat, bark, love.
