There has been talk of a Pin Market crash since I got int the hobby a decade ago. TAF and TZ hit $2800 - 3000 and the REC was fll of people declaring that the bubble was about to burst on this thing. MM hit $5000 and people were beside themselves and foaming at the mouth for that crash tha was going to dump $3000 MMs back onto the market. WH20 hit $1800 and it was surely time for this thing to unwind.
It isn't happening. The increase in prices in this hobby is nowhere near reflective of the crazy inflation realized in just a few short years in the Muscle Car hobby. And it isn't like those cars are going for pennies on the dollar now, either. There was an adjustment due to hyper-inflation - which was arguably caused by the auction industry (particularly genius Barrett-Jackson marketing) - in the auto collector market, which has since stabilized and continued to increase prices since the adjustment. There is no equivalent to this phenomenon in the pinball hobby. The prices have risen slowly and steadily - that isn't the kind of inflation that causes dramatic market correction. The only thing that will cause dramatic rollback on this hobby is if Planetary Pinball licenses someone that actually starts reproducing old titles at prices lower than the current market - MM, AFM, MB, etc....
