The OT is irrelevant in this respect - the situation is entirely different.
In this case, three films were given release dates nearly three years before they even came out.
Every detail of marketing campaigns, toys, press, every ounce of ancillary anything was planned out to the most minute detail.
Yet, they didn't sit down and plot out the three films they were placing at the center of all this. They had every single possible resource at their disposal, their pick of the top talent alive, and they decided to just wing it on a one by one basis the center of the entire venture.
No one is saying that every shot needed to be planned out for all three films in advance, but it is ridiculously clear now that all the naysayers when Disney purchased Lucasfilm ultimately turned out to be right. Disney was solely concerned with everything they could sell and how much money they could milk out of it, treating the films themselves as afterthoughts.
