Here is a valid question though, is Falls Lake that impossible to move? I could easily see them move that down northeast of property, next to Little Europe; and that they may be fine there and that they can still have something like that on the lot.
And as for Supercharged, yes; there would be some concerns. But I think as the Studio Tour keeps transitioning due to changes needed, I could see it's days while numbered; the IP could still have a potential future in the future second gate.
Psycho House, may be the harder cookie to crack; as I don't know if that's a national landmark, but that I think it is rather possible that they can do it.
Also, is there a grand site-plan of what Universal fully owns for the property? Thay may help answer some of what I'm trying to say.
