It seems like Fenix is really the only company that can do that. By changing the product so often, I assume that it makes the older stock harder to sell. Novatac might be more costly to produce, therefore they don't want them to go to waste or sale.
the led replacement race is very expensive; the high-end American manufacturers (Novatac, Surefire) can't afford to play that game. some of the other American manufacturers (e.g., innova) don't even offer the new leds left.
I wouldn't be surprised if Novatac came out with an updated model, but who knows. Maybe they are waiting for v-bin SSC's, rather than make a switch to a Cree.
In time NovaTac will update their emitters.
They will need to work on their drivers as well in order to keep runtimes decent.
Battery technology is not improving as quickly as emitter technology.
A 200 lumen NovaTac which will only put out 200 Lumen for 10 minutes is just about useless.
It wouldn't surprise me that when emitters came out which doubled the amount of light they put out that NovaTac would consider a new form factor with a 2 cell design in order to keep up with the current demands of new driver emitter combinations while maintaining run times.
