Uh. So anyway…
I should point out Anakin and other prequel characters appear in Disney theme parks, although Mr. Binks is noticeably absent. There is still a moderate level of prequel merchandising even though the new films dominate the toy lines and Episode III was 12 years ago.
I guess? Theme parks feel like a niche area to me, but I have no idea what kind of broad appeal they have beyond the families who can afford them. The Star Wars Land idea is coming I guess. And there are a lot of toys out there I suppose. But talking of basic stuff like coffee cups, socks, t-shirts etc. there’s usually Vader and all the familiar faces. The Story Spinoff movies are all catering to the same idea, though obviously a few winks to the PT are present.
