Love this idea (sort of a take on stuff they've gone with in movies like Blade Runner, 5th Element, etc.) but the reality is, it wouldn't age well because Disney wouldn't be bothered to update any of it. Seeing all that stuff for the first time would be awesome. Seeing it all exactly the same 15 years later on your 15+ plus visit back but with parts not working correctly anymore wouldn't be.
If they could be bothered to keep up with the maintenance and design it so that the content could be easily updated and start out with a large basic catalog of stuff so it wasn't an instant and obvious loop and then swapping some of it out from time-to-time (maybe annually) so it didn't immediately go stale with people knowing it all before it's even said or seen, it would be great, though!
None of this would be hard or expensive. Even
I could probably get something working with an uneatable interface using few arduino boards and I'm sure they could have their existing bloggers pump out enough Disney-approved content during down time to keep it going indefinitely... but they won't.
