I think this is Disney’s endgame. They already own a huge part of the market, and with Disney+, they will be able to control what is placed onto the screen. They do not have to split the money with movie theaters. They don’t have to reveal how much money their movies are making. And most importantly, it’s convenient for the consumer = people become dependent and we can raise the prices as years go on.
Wouldn’t be surprised if the Star Wars franchise becomes entirely shows on Disney+ in 20 years.
