If the next movies are in any way PC, Disney will likely lose big time over this. They paid something like $4 billion dollars for the whole thing.
If you throw in the cost of making the films, each film is going to have to make a billion dollars and they are going to have to make at least 6 films to get their money back.
The money is going to be in licensing: toys, theme park attractions and more. The films are just commercials.
PC is an understatement. Ever notice now that on SyFy with all these cheap knock off disaster movies involving storms, tornados with sharks in them, land sharks, ice storms, et al, that the term ‘climate change’ and ‘global warming’ is given as the cause.
I’d expect a future Star Wars movie to be based on something along the lines of “the demise of XXXXXX (Rebel Alliance OR Empire) was due to global warming across multiple planets.
If they stick to already Lucas-approved canon, then the story will follow the fall of Han and Leia's son Jacen Solo to the dark side (he become's Darth Caedus) and his twin sister Jaina's efforts to stop him.
If you go back and read what George Lucas himself said about the Star Wars franchise, he had the vision to keep the marketing rights. He made 10 times more money on product marketing the Star Wars brand than he or the studios ever made from theater ticket sales.
Disney, the masters of marketing, know this as well.
