Then why bother discussing anything or even reading a rumor forum?
We don't know what, exactly, any of the final products will look like.... Even the concept art released by Disney doesn't EXACTLY show what the final product will be like.
Half the fun of this forum is to trry to "look into the Disney mind" (so to speak) and try to figure out what they are or will be doing.
So far
@MisterPenguin and others have done a pretty good job. So what if it isn't perfect? It gives us a pretty good picture of the future. In fact, the early on layout posted on here matched what Disney released at D23.
As for sight lines, well, of course the current state shown in Google dies not represent what the final view may be, but it is a good approximation an I bet Disney did something similar in their planning (more detailed and accurate because, well.. They had all the details).
(Walks over to discuss gondola derails with
