Originally posted by Des What I see from Japanese dealers is the K-1 holding its value remarkably well
Here's what eBay currently shows, for the 10 recent sales of used K-1 in excellent working order, excluding bundles that include major accessories such as lens or grip, and excluding those where the condition is new, mint, or near mint:
(Ignore the first two listed -- the two with the lowest prices -- as their descriptions say they are faulty; I'm looking at only the last 10 in the list, with the highest prices).

Those ten range from a low of US$935 shipped to a high of about US$1,245 shipped, with a median of about US$1,075 shipped.
That compares to the current B&H Photo new price for the K-1 II of US$1,800 shipped. I think that's similar to what the K-1 sold for when new.
I don't know what used examples were selling for before the K-1 II was released, but I doubt you could have gotten one in perfect working order for US$935 shipped, or US$1,075 without even trying to get a good deal (the median price).
It's harder to get a read on current used K-i II prices. No recent sales match the conditions above. The one that sold for the lowest price was actually a K20D, judging by the picture, not a K-1 II as listed (auction #174633263877).
Looking at current Buy It Now offers, and ignoring examples where a K-1 was upgraded to a Mark II, there are 2, with a low of US$1,486 shipped and a high of US$1,517, making the median US$1,501. That's a lot higher than the K-1 median but not really an apples-to-apples comparison.
I think we all agree that the current prices on the used market for the models under discussion are the result of the current tension between supply and demand. When K-3 III buyers -- some of them -- receive their new K-3 IIIs, and start selling off their older bodies, whenever that starts to happen, there's going to be a surge in supply. There won't be a significant corresponding surge in demand because the release of the K-3 III won't directly cause people to start buying up used older models. That shift in balance between supply and demand -- an increase in supply with no significant increase in demand -- will push prices down until prices are low enough that more buyers show up to buy the additional supply.
I think the KP will be less affected than the others since the K-3 III does not have features some KP owners value highly -- lighter weight, small handle availability, and flippy screen. The KP will remain the best way to get those features, so some KP owners won't be interested in upgrading to the K-3 III. But other KP owners are in it for features that are improvements over the K-3/II but will be available or bested on the K-3 III -- improved high ISO performance, USB tethering, handheld Pixel Shift, 5-axis image stabilization -- I'm not sure offhand if there are others. Those KP owners, who went from K-3/II to KP, likely are looking forward to upgrading to the K-3 III. No doubt still others have mixed feelings about upgrading from KP to K-3 III.
The effect on prices might be small and temporary, but I doubt it, because the availability of the superior features and performance of the new model will push down the market value of the features and performance of the older models. If it were not so, than all the old models that are still in excellent working order would still be selling at the prices they commanded when they were current models. Obviously they don't; for example, you can buy a K10D today in perfect working order for a very small fraction of what it would have cost before the K20D was released. The availability of the K20D pushed down the value of the K10D's features and performance. Then the availability of the K-7 pushed them down further. Then the availability of the K-5...etc. etc.
Eventually the downward curve flattens out and very old flagship models in excellent working order start to converge toward roughly similar market values. Then in the very long term some might start to rise again if they gain value as collector's items.
