So I saw a Jon Snow spinoff is coming and GRRM was talking about it. Why HBO still pays him after he screwed them over by refusing to finish the books is beyond me.
Since they didn't allow Jon Snow to fight the Night King due to girl power reasons, I can only imagine he will be upstaged by a smarter more capable female warrior of some kind. That is just my guess based on modern entertainment.
It was never any secret that Westworld the TV series is based on Westworld the movie.

Based on Westworld the book written by Michael Crichton who also wrote Jurassic Park. The series always had a decent pedigree to work from but leave it to HBO to completely ignore it all.
