I was JUST going to post this myself.
Many months ago now, they teased that the have included concrete airfields for appriate airfields, that the have improved the coastline and spread farms, windmills and bridges across the map. They hoped we would see it soon TM.
The airfields from that video mirrors the airfields shown in the Spitfire trailer from over a year ago. They are FAR better than what we have now (I think it is the same in the above vid, but that one seems to have the old shader, making it look not so good). The odd thing is that the map are recieving small "quiet" addons, like the new estuarys, some field textures etc without mention.
A written update with some screenshots would go a VERY long way here instead of sitting in the dark for months and months. I know that the default answer is "they will show when there is something to show", but surely they have something they can drip feed us a bit with regarding this map.
Could we see a new airfield or coastline for example? Will speedtrees be implemented or not?
Info and screenshots keeps the hype and interest fresh. Hope there will be some more info soon.
