I doubt we will see any further expansion of where we can land for a few years, season 4 at the very earliest would be my best guess, though FD may pull it together and have something during season 3.
As there is very little to do on the planets we can land on and even less to interact with at this time and season 2 has nothing more to add (announced) in this area, its either what season 3 is going to be about or season 4 and my money (not that I am going to be spending it) would be on season 3 offering very basic 3rd person out of your seat in your ship, out of your ship in some space station areas, out of your ship in some multicrew ships, walking about eva on current planets and moons.
