Again, I think some people read it as solid land, but you're dealing with elevation changes and weirdness that the paint-over concepts artists frequently present wonkily either due to oversight, miscommunication, or misinterpretation of what they're given. The visual cues were there to surmise that a stream would be maintained west of the Piston Peak cascades, and the area near Big Thunder was so visually compressed that pretty much anything was possible. The point is that I don't think the plans are meaningfully altered when comparing the pieces of artwork considering most of the things that were announced about its structural makeup were already guessed. They may have refined the Cars "look" and the park-related finishes of the land, but I think all of the major structures and features will still more or less appear where they were originally shown (the Grand Fusel Lodge, the junior attraction, the geysers, Piston Peak, the stream, the boardwalk, the finish line pavilion, etc.); they were just playfully oriented for the new artwork with backstage elements like the queue/shop building excised.
