well , not one can really answer that beside Frontier i'd say. just hope that their goals will be to make the game more smoother, and let their entire ideas flows into procedural generations. It sad that the ability to visit a planet wont make out at release, cuz it feels like the game isnt complete. but since its a digital thing, they can upgrade it thereafter , hopefully itll be free...
id like to see Elite Dangerous with not very much limitations as in explorations... planet visit is a whole big thing to do , but it will makes the galaxy alive by seeing cities, excavations, facilities, civilisations , and such things.
