they will all go down and keep going down unless something raises the demand. also note that as the prices drop some demand will be gained by ppl that will not or can not afford 3k for a snake. this also has some to do with the economy and how bad breeders and deals have to sell or can they hold on to them. pieds will surely drop this year as will clowns. recessive traits hold because it takes longer to produce them in quantity and unless you have 2 visuals you typically will not get more than a few from a clutch. codoms and doms will go way down faster because of ease of production.
even if they are nice ones or not so nice ones they will all go down eventually thats part of supply and demand. some ppl just dont care what they get and some shop around for the nicest or the cheapest price.
