Prices ALWAYS drop at that magic point where there is enough animals produced to actually have a sales-vs-customers line. At that moment, the price drops dramatically. Everyone who was willing to pay $50K already has the animals they want.
It's the natural progression in pricing of new morphs. If you want in on the first tier, you buy the high price first animals available. If you're okay being a couple steps behind in breeding, you wait for the price drop.
Simple.
