No they won’t. On newer games the base model might drop but so will features. This is to sell games for actual operators. New high end games..... I foresee a lot more trading going on.

Used games - prices won’t drop significantly but quality of games will increase - people will put more effort into fixing them up.

You’ll see pins in rough shape devalued. That’s how it should be though. Remember when blown out MM’s we’re going for 8k. Ya that was stupid. That’s the bubble that will or has already burst.

But they are all hobbies primarily based on disposable income and nostalgia.

Not sure its price so much as quality - ie B/W from the 90s that are in rough shape aren't moving at "new" prices. There are more parts/plastics etc. available and owners are fixing them up - those will get bought at the "new" prices.
