I suspect that the biggest restriction on actual production would be where you can sell the stuff at. Most installations would probably be harder and harder pressed to justify any sort of continual force upgrade programs unless and until there's another big Boskonian push to try to take over... and that's unlikely, because the Fen showed after Serenity Valley that they have the will to go to war... and the force multiplier to succeed in such. While there might be incremental "mark" upgrades to existing ships and equipment, it's likely that some of the heavier hitting stuff has slipped down into a "one off" production mindset, just tinkering to see if certain things are possible, because the resulting product line wouldn't sell well enough to justify the tooling up (or waking up the robofac and feeding it).
Basically, lack of sufficient demand will probably keep things somewhat cooled down. Yes, some might play a little too much for some people's comfort with their nice, explosive toys... but over the last five years, that's basically all it has been, playing with toys.
