They don't stand a ghost in hell's chance of doing any of that. The project is tainted, toxic, and squarely in the realms of DNF, NMS etc. The only people they're going to appeal to, are already engaged - and are the only ones left. That's why on Reddit, RSI forums, Spectrum, media news comments, it's always the same Usual Suspects.
And considering the nature of space combat games, they're already tapped out on their potential install base. SC doesn't have anything that ED doesn't already have - and does better. When you look at COD:IW which did well, but not well enough to match its predecessors, that's the sort of metric people should be looking at as well.
Luckily for them, unless those games and us devs, all their money has come from pre-orders (as well as loans and investors). So they already have most - if not all - of the money they're ever going to get from the game.
It's never going to recover. All we're doing now is speculating on when it will collapse, and what form said collapse will take. I still maintain that it will be a sudden collapse; not the slow burn that most are thinking, as that one requires consistent funding to keep 350+ people in 4 worldwide studios in jobs for the foreseeable future.
