By the sounds of it, Darth Loner is probably thinking along of the lines on being able to play all over Coruscant. Essentially, what we see in the films as well as EU, etc.
If that were to happen, I would think the whole game would played in Coruscant if that were to happen. Otherwise, I'd be skeptical about that idea. I doubt that the idea is being hardly considered when there is many other planets to battle on.
