After some back-and-forth over the years, I'm now of the opinion that even if Star Tours isn't kept around long-term, then the ride system should be retained basically forever. It's just an incredibly engaging and fun simulator system with lots of potential movement profiles, and that they can also reprogram and refresh incredibly simply and whenever they feel like it. Neither Falcon or any of their new simulators actually replicate the pure fun of Star Tours' motion effects and 3D visuals imo.
If we can't keep Star Tours, at least give us a Big Hero Six ride for the Japan pavilion, or something like that with the same ride system. I know they're ancient rides, but they're just really solid and work great as those simple 25 minute wait diversion attractions between E-tickets and dining.
