Does 2.0.0 numbering mean something new features other than Edge integration coming to DCS:W?
Yes. Sith made the following comment on the official forums:
2.0 is going to be full of goodies, some of which have already been touched on in previous announcements, some that havent.... it will take time.... and patience... I love that its name 2.0 now, it gives more meaning to the changes coming... its not a simple patch....
