Segments swapped out I'm sure. HarmonioUS is a very easily modifiable show. A lot of people want Coco to be swapped out with Encanto which I would hate. I like Encanto as much as the next guy but at least Coco's involvement actually makes sense thematically. "The music is my language and the world is mi familia" is essentially what HarmonioUS is about anyway. I'm not sure how a movie about generational trauma would fit into that mold.
Unless the show is getting more pyro, an inferno barge, an expanded harbor to store the barges, or some type of Illuminations comeback using the barge technology, then I don't want this "2.0". I love the current version of HarmonioUS. I've connected with it and I've even had family memories related to the show and I see that it has grown on people a lot (not everyone though). Though I was confident that an IP show about world unity would work (which in my eyes it did), it was still a shot in the dark for Disney. Why take two shots in the dark when most of the GP think that the initial product was great to begin with?
