I didn't have much time to post this so I haven't read all the other posts. sry if this has already been said but did anyone notice that in parts of the traileryou don't see the map? I think Nintendo has done this so that it won't spoil parts of the map. In the part where Link uses the iron boots you see it says "1<MAP>2" where the map should be, but in other parts it says nothing. I think it has been digitally altered so that some parts of the overworld don't get spoiled. I focused on the map to see the relation between Link and the overworld, and it looks to be a pretty good size.
Well I'm out.
