I find it amusing that 327 posts later and no one has actually proposed a somewhat reasonable basis for the release of a third faction beyond "I have money and I must spend it!".
I find it amusing you don't think Demand isn't a reasonable basis to procure supply. That's pretty much all the excuse a company needs to make something. People want it. They will pay money for it. Why not try a smaller print run and see what the sales look like.
When did I say that? All I am saying that this 'demand' is actually for more ships; which by the way they still releasing AND are showing no signs of slowing down the release schedule even if the more identifiable ships are already done, and not for a third faction in and of itself.
TL;DR They are aware of and are meeting your alleged demand. Calm your farm.
