Sort of. It's the laws of Supply and Demand. When Demand is high, the parts price will stay higher than depreciation says it should, regardless of Supply. If Demand is low, price drops.
By the same token, when Supply is high, competition drives sales prices lower, if Supply is low, prices go up regardless of Demand.
But that's all decided by what the Market will bear. 10th Gen isn't in high demand. It was the first gen on the lga1200 platform, so apart from the 10900k, most ppl prefer to go with the 11th gen parts. Which is what most stores still carry a little of. Once 13th gen arrives, 11th gen will all but disappear from shelves, mostly be on the Used markets, where 10th Gen will be cheaper.
What you'll likely find is the 10100 to 11400 prices will hit bottom. Nobody wants those parts, and most Dell's and HP and Lenovo have them. What'll be more expensive will be the 10700-11900k cpus as ppl gouge prices on upgrade buyers, ppl moving from a 10400 - 11400 to a 11700 for the extra performance and/or cores.
Upto the point where the 10400-11400 starts getting scarce, then it's price will increase. For as long as ppl still want them.
