Since we won't be able to fly in the old areas.....

[ElHeggunte]

The old maps don't have "blank spots". The edges of the maps are designed the same way that the 3.0 maps are. You can still "see" stuff in the distance, but it's just a backdrop. When you hit the edge, you hit the invisible wall, just like in 3.0 maps. There's no "blank spots" within any of the 2.0 maps.

If SE implemented flying in 2.0 zones right now you would probably see a bunch of unfinished textures and plenty of areas where you would pass right through the ground if you were to fly over or land on anything we couldn't get on or see the top of before.
