Pinball is being fed mostly by nostalgia. Unfortunately that means that eventually there will be a time where the people who grew up on high-energy pinball (80s/90s) eventually are not collecting because they're retired or dead. I think you see that even with the EM market now. EM pinballs command a much lower price because the population who grew up on them are aging out of the hobby.
I'm enjoying the games that are coming out now, and it's certainly nice that I'll get to play more new games. But I'm not under any illusions that pinball will last forever. Entertainment is in the home on portable devices and available very cheaply. Adults in 30 years will collect antiquated iPads and not pinball machines.
