It’s not that odd when you recognize that many Disney projects are announced very early in the project development process. At some point the bellyaching about this is just deliberate ignorance. Yeah it’s kind of dumb but it’s what happens, so there shouldn’t be any surprise by the lack of visible work for some time after announcements.
That they’ve done work with other figures doesn’t really matter. Things like available power and data are not the same place-to-place, not to mention the logistics of making sure it is available within the confines of a 50 year old facility that was not designed for this scene, modern power systems or modern show control systems.
This install has not been done before. This location has never before been considered as a location for this or any other figure. It’s also the result of organizational issues that likely were not considered in the early feasibility stages of work.
