Mr. Man from Holland, yes, the selling price for used Schoeps (and Neumann, and AKG, and Sennheiser, and DPA) equipment will probably rise to some extent. But the effect is due to varying human perceptions and circumstances, so it's hardly automatic. The extent and the timing of it can't be predicted exactly.
The thing is, prices for good European microphones are mostly so high already that many people who want them would need to go earn (or find, or print) more money before they can buy them. So your equipment can be worth more on paper than it was last month, but there may not be many buyers waiting all sweaty with their demand pent up and with dollars in their hands. When that happens, you don't get bid prices as high as when there's overt competition among bidders, and you may have to dangle stuff for a while longer than previously, as people adjust gradually (and despairingly) to current market conditions.
