Just a side note for the above

It has not been confirmed that the areas/zones/regions shown on the map will be the only playable areas at launch, or merely what they have added for us to see so far. They have confirmed that areas are saved/reserved for future patches/dlc/expansion(included in subscription), so it is possible that either there are more maps that will be available at launch or that is all we will have access to at that time. However it is also good to note the the zones/regions indicated on the map would be safe to assume they include their own subregions as well
