We're probably looking at a halo effect ?

Similar to concept car demoed at trade shows, we get an idea of Disney's technical engagement, and some of it will perhaps in some way or form get applied into future products/attractions.

The only thing worse than not getting the concept car, is getting the concept card after it’s been through the development cycle. Pontiac Aztek comes to mind as an example

I thought that, aside from being among the least visually appealing mass-produced cars in history, the Aztek was pretty well received -- basically an early version of the "the American lusts for some combination of a Gremlin and a Wagoneer" idea
