This isn't a new concept. Remember the brass market of the 1970s and 80s.
Most of the manufacturers have product out there that you are familiar
with. If you don't like their product to begin with, then by all means,
don't order. On the other hand, manufacturers can't just bet on the market any
longer. They have to sell product or it sits on the shelf.
A question. If you were a manufacturer, and a good one, what would you do
the ensure you didn't bring a massive number of models to the market that
people won't buy?
