1. AI based predictions
Inverse and Unanimous made a number of predictions, with swarm AI, which combines machines and human experts in some kind of hivemind with magnets
Is Bran the NK: No (low confidence)
Will Tyrion Die: Yes (low confidence)
Will Jon die again: No (low confidence)
DataRobot made AI based predictions too - and Dany is the most likely to die
The Technical University of Munich also used machine learning, neural networks and models that used techniques related to Bayesean inference to make A song of Ice and Data. According to their analysis, Arya and Bran stark are very likely to die, while Dany, Tyrion and Jamie survive.

Reconstruction of the redacted text
Five central characters will make it through all three volumes, however, growing from children to adults and changing the world and themselves in the process. In a sense, my trilogy is almost a generational saga, telling the life stories of these five characters, three men and two women. The five key players are Tyrion Lannister, Daenerys Targaryen, and three of the children of Winterfell, Arya, Bran, and the bastard Jon Snow. All of them are introduced at some length in the chapters you have to hand.

6. The Sun interview on the endings
Gwendoline Christie (Brienne)It's so... it's so bittersweet you know. It's devastating, and it's awful. But in many regards, it is one of the most exciting things I've ever read and been a part of.
Isaac Hempstead Wright (Bran)
In my opinion we've ended it in the most convincing and compelling way possible. I think we've wrapped up really in the spirit of Game of Thrones, which is all you could ask for.
Liam Cunningham (Davos Seaworth)
The Show kinds of holds a mirror up to life and society and stuff like that. It'll satisfy some, there's always going to be people it's not going to satisfy. All we can do is try and tell the story.
Pilou Asbæk (Euron Greyjoy)
I can tell you something, I'm probably the only guy with an happy end.
Jerome Flynn (Bronn)
I was really really relieved when I read it, and the more I think about it the more I think what an amazing job they did as there is a lot of pressure trying to finish Game of Thrones. I think the boys did really well.
Mark Addy (Robert Baratheon)
We've got to... the living have got to beat the dead. Surely. I mean you can't have... can't, I know you'll see it could be... it could end in any way.
