OK.. I think I got it...
I know that in the original plans for WS, the American pavilion was planned to be a large glass building right at the main entrance, with Canada and Mexico on either side. They scrapped that plan because they felt that the American pavilion would block the view of the lagoon and other nations. Since they were changing the location away from the entrance/exit to Future World, they also changed the building design to be the Colonial style we see today, rather than the futuristic glass building.
And hey, if that's not the answer you were looking for, then there's some free trivia for ya'!!
