...well, kind of. They presumably made at least enough money to cover the costs of making the ships, at least, since they're going for more of them.
But cosmetics are a tiny part of ED income overall (<10%, probably, from the figures in their official financials, even with the boost from the ships). A new ship that can be done cheaply [1] and pay for itself, great. A major new feature would need to get people persistently spending several times more money than they currently do on cosmetics - i.e. not merely substituting their existing ship paint spend for interior cosmetic spend - to be worthwhile.
Meanwhile something like colonisation or Powerplay which brings general positive attention to the game, boosts activity from veteran players, and gets sales to new players up brings in a lot more money (and more cosmetic sales opportunities, therefore, but the new game sales remain the major source of income)
[1] Note that the new ships don't have new interiors, which is probably a nice cost saving. But also suggests that "lots more interiors work" isn't in the plan.
So I just don't build a 2nd Coriolis? My system stays as a 1 Coriolis system forever? Or until I have only one slot left? That's pretty sucky.
