you would assume they would work in a similar style as a car manufacture, when determining how long to run a particular car model for, have model projections for best case scenario if the model sells for how long they would keep the model on sale for and production numbers and if it succeeds those number they would continue selling, and if it didn't they would end it early, if they have set a number for limited editions that is very limited in numbers they would stay with that if they have advertised and continue selling the base models, might even revamp and alter the limited edition and make a second limited run, like car manufacturers do also.
it would be very interesting to see how many of these they sell.
