Without the books to guide the shows plus condensed 6 episode season is leading to a pretty piss poor Season 8. Everything is so rushed and so poorly set up.

Either way, if I have to guess...

Kings landing is toast
This will be the downfall of Dany
Arya and Hound goes after Mountain...maybe Hound saves Arya but dies...
Jaime is the little brother that kills Cersei...
Tyrion, may actually try to save Dany and pays for it
