Im not sure how people would expect it to be any different given that the sequel is a direct sequel set in the same place.

Also, key point, we dont know how big both the underground (hinted at in the first trailer with Ganon being sealed under ground with the green miasma and shit) as well as the sky islands. If both of those are reasonably big and the map itself is completely repopulated, perhaps some new villages added for example, to show the passage of time. Then I dont think it would be an issue.

That said, come day one and it is just the same shit with what amounts to a few new shrines? Yeah, that would be REALLY bad.
