So to my understanding the V6 world is there, and you know what the map looks like, all you gotta do is finish building things and implement the software stuff like auction, etc.
So why not do a V6.0 map, so we can all see what the map will look like? So like, if I were looking for a chain of islands, or a large mountain, to build on, once V6 is ready, I could find it and sort of have everything planned out beforehand, so we don't spend the first week of V6 looking for a suitable location for a town.
Unless it would be a spoiler and you want the map to be a secret, then nevermind.
