about the high prices....

you can think of it this way: its opposite to old rare non-living things that fetch high prices. like some really rare postage stamp or a baseball card. it used to be really common and low value, but it got less common over the years to the point of being expensive because its now really rare. until the item is so prohibitively expensive that only well-funded top collectors can buy it.

new BP morphs start out really rare and really expensive, and when a really low number is available, they are so prohibitively expensive that only the top breeders can afford it. and then they get more common, price goes down, more enter the market, and the new morph makes its way to medium-sized breeders and well-funded small hobby breeders and so on, until finally it reaches a reasonable price for a pet.
