Considering that Shirogorov have improved their production and output speed in the last year or so, I'm not all that surprised by this at all honestly, though it has come at the cost of not seeing nearly as many of the more rare configurations anymore, like the 95CF or any models using Vannax35.
Shirogorov used to make knives at a much lower rate; almost as low as Todd Begg knives as a matter of fact, and we ALL know what they did to the prices of both companies. As a result, they also had a very long waiting list in Russia, and another one for dealers in the US that was equally as long if not longer. Once they got the recognition for their quality that they deserved, they blew up in price exponentially, as one would expect in this market at this point.
Today, there is no longer a waiting list to buy from Shirogorov in Russia to my understanding, or if there still is, it is much shorter than it used to be, and that is because they have greatly increased the speed at which they can produce knives, to a similar place as CRK it seems. In addition to that, you now have a market where multiple dealers and sources can get and sell their knives, and there are also private dealers like Vladimir here on the forums. The increase in competition decreases the price so that they can compete, and that benefits the consumer.
Like others have said, I doubt that some of the more rare configurations, like the 95CF or any of the models done in Vannax35, will drop all that much unless we see precedent for it, but the more regular models, especially those that simply use S30V or plain finishes, will probably stabilize just about where they are now or maybe a little lower.
The fact remains that they are fantatstic knives either way, and I feel no issue with what I paid for my 95T M390 over a year ago, nor what I paid for my 95CF S90V more recently (those are just the Shiros I still have...I have handled and owned too many Shirogorovs...). I cannot say for sure that I will keep BOTH of them if this trend continues too much just because financially it isn't a good idea, but my 95T M390 will probably be a knife I always keep forever, and that is something I am abut 99% sure of as long as I have a say in it.
