We probably wont let you / be able to have this all in one continuous area as with the distances involved we will have some serious scale issues and floating point problems to overcome. Currently its set up that each one of these locations is its own space level / instance and they are linked by a higher level system map.
Plus it would be quiet boring to fly between them in real time.
I'm not ruling out a system that allows all this on the same map - but its not likely given the real world scales we are going for. We may do something that lets you fly in a direction and then after a while just streams in the new location though...
