As far as I know the 2nd gen UCS stuff are computer designs, so depending on the fabrication method either the masters or the moulds are 3D printed.
Also the Dragon Lords pictured in the last rulebook look more detailed than the earlier models, so I think they actually got reworked, just not to the level of Spartan’s later work.
Anyway, it has been over two years now, I have six fleets gathering dust while waiting to be completed, and I’m not happy about that.
Like I said before, if they don’t have the intention of actually doing something productive with the stuff, then why not sell it on to someone who will do something productive with it.
At the moment the vast majority of the UCS models are still competitive quality wise, and there’s no competition whatsoever, but those circumstances aren’t going to last forever.
They are just burning daylight.
