Here's my wishful thinking:
Sansa will end up on the throne. Either because Jon dies or he doesn't want to rule. I would like to see Lord Varys as her hand.
Dany already saw her reunion with her child and Drogo, so I think she will die.
I would hate it if it was Gendry, Robert's rebellion was based on a lie.
I think Cersei will kill Tyrion, then Jamie will kill Cersei. Jaime will then die, probably by his own hand as his whole family is gone.
If Jaime doesn't kill her, then maybe her loyal zombie mountain will become a white walker and do it instead.
Arya will kill everyone on her list that isn't already dead.
Sam will do another absolutely courageous thing and will be hailed as a hero.
Bran will go off to live in his tree. I would like to see his loyalty waver towards the white walkers, that would make him a little more interesting. I feel like he and Melisandre will have something to do together.
Brienne and Tormund have giant babies.
HODOR. The End.
