I'll admit I had my "Jim Hill distrust" phase for a long while when he posted an article that seemed fake about another ride film for BTTF: The Ride. Everybody kept shaking their heads about it and I was really dismayed about it. But much to my shock, he was... absolutely right. It's even talked about in the new Back to the Future coffee book and even director Doug Trumbull has done interviews discussing about him reviewing it before agreeing to redo it. Recently been listening to his podcasts with Len Testa and they're pretty accurate, funny and interesting. If you can't stand him, that's all well and good but I don't think he's super untrustworthy at all.
And we all know that things change behind WDI doors all the time. For god's sake, over half of the New Fantasyland expansion was slated to become five meet-and-greets for a good two years before changing to include SDMT, and it was people like Jim who were notating that at the time.
Back on topic, I saw Zootopia again last night and reviewed the details of the entry train scene (it is a train, not a monorail)... it seemed like something they could enhance using similar tech that is featured at UOR on the Hogwarts Express. It's a lot of sealed windows, especially that top dome Judy looks out into. I know people probably want an actual city rising out but with the Safaris next door, it's probably more practical to travel guests into a show building, using the windows as a disguise. An enormous show building could immediately drop guests into the city and have completely climate control.
Man the possibilities for this are just too awesome for Disney to ignore.
