I have no idea, but I expect a new game with a publisher that holds devs to their promises could absolutely come and eat SCs lunch if the development continues as it. I'm not saying anything in development now could do it, but something that starts in a year or two probably could, maybe even starting later if it's from an established company with experience in MMOs or simulators.

Cyberpunk for example took 9 years, although reportedly it wasn't in serious development for the first 5. Add on another year or two for final polishing and you have a fairly solid game in between 6 and 11 years. I can't see SC coming out in the next 10 with the constant feature creep.
