I'd be interested in finding out how the position of Skyplex would affect the USO/IOA skyline. Is there going to be a 500 foot tower appearing behind Hogwarts and ruining the illusion? If a tower that tall were to be built that close to Disney, wouldn't they throw a fit too?
I want to see Skyplex succeed, and I definitely want to ride that coaster, but I understand USO concerns over preserving the immersive environments they've spent billions creating.
***Edit: Looking at Google Maps and drawing lines from different areas of Universal, this really doesn't look like the tower would be all that intrusive to the Universal skyline, and for the most part you would expect to see a roller coaster looking toward the Skyplex from almost anywhere in either Universal parks. I did some calculations based on sight lines and distances, and Universal could always just build a 175 ft tall wall along Hollywood Way to ensure none of their guests would ever have to see Skyplex. Seems resonable.
(Just kidding, please don't think I'm serious about my musings from beneath a foot of snow here in the midwest .)
