I think you doubt the next generation. With as many pinball video games being released, and kids to play them, eventually those kids will want to play those pins for real.

It's like 5 years ago, there was a sudden resurgence for kids wanting to listen to records, RECORDS! And look at all the kids riding long skateboards, I haven't seen anyone ride those since the 70's. Everything comes back around, eventually. Even if it gets so bad that medieval madness machines start selling for a thousand bucks, eventually when pinball catches on again (and it will), they will be the first ones people will be after.
