Quoted from Luckydogg420:Jamie and Bronn will both be captured.
Drogon will die (poisoned bolt to the shoulder) just like Khal Drogo did, with a shoulder infection.
Arya will kill peter Baylish with the catspaw dagger.
Vayres won't be around for long, unless he has one more trick up his sleve. His story arc is done.
Greyworm won't make it back to Mesandi, their sex scene sealed his fate. G.R.R.M builds these attachments then tears them apart. (Dead by the end of the season)
Tormund will die at eastwatch by the sea. There will be a big battle. I don't expect him to live.
Everyone with a valyrian sword will live till the final battle. Jon, arya, brianne, Jamie, and Sam.
....that is all for now. I've got a prediction for how it will all end, but I think I'm right and don't want to spoil it completely.
Those are all to easy and obvious to be true. Not saying some of it won't come true...
The part I can' figure yet is when Bran tells Jon his past and he tells everyone what Littlefinger did. That will get the ball rolling.
Cercsi will die by Jamie, it was part of the prohecy.
