Considering where these plans came from, what they show and the level of development, I'm confident enough to say that this is the direction Disney is going.
No trolleys.
No I-4 work, which would naturally include the state and county government's involvement. Frankly, I'm not sure I'd want to see either. They look to be pouring way too much money into this as is. Funny, UNI built City Walk and while there have been places that have come and gone, they have never needed to fundamentally go in and alter the place.
Again, say what you want about Disney being incredibly cheap (because they are), but they sure don't mind spending billions when it comes to a giant datamining/trip planning/back of the house IT system, redoing a mall into ... well ... a mall and building countless hotel rooms and timeshares.
They just seem to have no conception of why any of that stuff exists to begin with. ... You know the four stale theme parks?
