My gut tells me that there are a lot more out there of any title than we think because our counting is biased by what we can count. Namely the numbers that we have on pinside but even with that we know lots keep their collection list private.
Most of the EM games that I see come up for sale on FB and CL are not from collectors but rather people who have had a single game in their garage or basement for years and are now looking to take advantage of the inflated pinball pricing. And everyday I see new games for sale.
I always get excited when a new person comes on pinside looking for tech help with an EM and I think oh good there's another one we didnt know about.
