Fucking game just gets more and more confusing the more you look into it. I saw someone assert that the Zonai structure Ganondorf is standing on isn't in any of the Great Plateau aerial shots and guess what? Yeah, it's not there. Other farther trees and some kind of tower and stuff is, so I don't think it's draw distance, and it has to be in the present because he's got a shrine and the Hylian version of the Great Plateau wall behind him in the trailer. We have an idea from the art book how big this platform is too, and it's just not there.
I really wonder how much the world will change over time in this game. It's crazy the story and even just our basic understanding of the world still has these massive holes in it.
