There is no way that will happen. The production schedule is already so tight that 5 writers (Benioff, Weiss, Cogman, Taylor and Martin) can just write 10 episodes per year, there is no way that one person could get 10 scripts out in the time HBO wants them to.
Well I wasn't really being serious about that.
You know I have always puzzled over the title of novel 7 "A Dream of Spring" , because the way things are set now , all hell is about to break out in the East and at the Wall in The Winds of Winter.
I fully expect the Other's army to breach the wall and Westeros to finally become aware it has totally the worst common enemy. I am figuring the battle at Meereen will be a really big dust up.
Then Dany and allys (if such happens) will have to turn West.
If the Others are making headway the East may have to help and a big Ragnarök.
(Except George may have Bran turn the whole thing into a shaggy dog story!)
One can never out guess GRRM , but it looks as if the climax of the series comes next novel.
"A Dream of Spring" is what?
I will have to read the speculation on these forums.
