From Katie Kilkenny at The Hollywood Reporter. And Sora does look pretty damn amazing, though will have to see what you actually get out of it, doubt it will be 4k images, at least for now. And Sora did blow my mind when I first saw it, and I think it will put people out of work for sure, though copyright issues may be what keeps it out of say advertisements.
Still I don’t quite buy that the whole 800 million expansion is killed because of this alone. I would say even with Sora you would still need actors, but something like this will likely help create virtual environments, and in that case you would need less actual stage space, but more high tech stages with something like Stagecraft installed. And for that you don’t need more stages, but to upgrade a few existing stages, and you can have the equivalent of all those stages.
