Either way, we had the Old Soldier series of cinematics from BFA, which looked great and actually helped flesh out the story. I would expect there to be some fully CGI cinematics in Shadowlands and one at the end of 9.1's raid seems a good place to stick one.
I would love the jailer to go and res Galakrond. If the screenshot location is kaskala, or other south coast area of Northrend, that is very close to the path of the titans which leads to gala. (although I'd expect the jailer to emerge above ICC or something)
