Doesn't it seem crazy Universal hasn't already purchased that land? I mean, the value of the "full Disney experience" (fireworks shows, events past midnight, concerts, etc) seems like it would be worth a LOT of money, and at some point Universal *will* be constrained by land as it seeks to build enough hotel rooms, maintenance infrastructure, and parking for visitors to 3 major theme parks + 2 water parks.
And who is to say that Universal will ever purchase it? Why not buy it before they build the new apartments and save money that way? Why hasn't Universal purchased the "Bell at Universal Apartments" which back up directly on Diagon Alley? That would be the *perfect* spot for a boutique Harry Potter hotel.
Final rant/question... doesn't it seem like we should be hearing about permits for a fixed transit connection in the next year or even couple of months? If it's a monorail / light rail, there will be a lot of work and collaboration with municipalities, in addition to huge capital expenses and considerable construction costs. The LAX people mover, which is scheduled to open in ~2023, just broke ground. This project would probably be of a somewhat similar scale (LAX peoplemover is 2.5 miles, almost the exact distance from CityWalk -> Wet and Wild -> center of new land).
The longer we don't hear about it, the more likely they go the bus or gondola route. My guess is that there's a very good chance they go the gondola route, and that the odds of a gondola go up every day we don't hear about transportation plans, because the construction and permitting for such a system should be much simpler.
