Everyone wants to back Disney's idea to come up with original storytelling, and I can see the reasoning. But that's just not what people expected or even wanted. People wanted the Star Wars they know and love. And so here we are. The question is, will Disney eventually give in, or dig their heels in and try to make money the hard way? Because I can make a strong educated guess that they have financial estimates that show much improved land merchandise sales with an OT retheme. I mean, look at how fast those Tatooine spirit jerseys are being worn all over the resort now. Its been out for maybe 1 week and its probably sold better than anything they have sold for the sequel trilogy or Galaxy's Edge besides the opening day shirts.
One can argue ROTR is enough, and that may be true, but Disney isn't one to leave money on the table, especially in a scenario where it would actually IMPROVE customer satisfaction potentially.
