If this is in fact the world map (they, Nintendo official sources, affirmed it anywhere?) all my hy hype will go down in the drain instantly, only 3 proper disconnected areas, and a Sky above it that is only 40 seconds by flight long from the west-to-east edges.
I don't care if the game is still 50-100 hrs long, it would only mean that we'll have to backtrack a lot, but we are only going to see 3-4 areas with different variations (like the prankster commet levels in SMG2).
And this was a scratch i made early this month, laying the known areas under the skymap.
