Yeah, the stretching that's been going on with this new map has been crazy. Don't get me wrong though, for all those involved at pointing these things out, the discussion is still cool and interesting, and who knows, some of these may very well be on-point.
I think it would be neat if part of the map were where the meat and potatoes of the game takes place (dungeons, towns, Hyrule Castle, etc.) but then the outlying wilderness is more vast, open, and mysterious. Kind of like the island in Lost, how the beach is the central location but then when they have to journey away from it there's a sense of mystery and danger; the unknown.
Not to say it would just be a large empty environment, there'd be stuff there to seek out, maybe some hidden dungeons and tougher enemies. Kind of like, if you venture out there away from the comfort zone you have no idea what to expect. I don't think that's the case with this game, but it would be cool. Imagine venturing away from the central areas and everything gets kind of mysterious and even spooky. Like you run across cemeteries, weathered structures, ghost towns, etc.
