I think it is very difficult to accurately say what pinball is going to do in future. Pinball is very different today then in the 90s. There are hard core collectors, fixer up ers, flippers, operators, business owners that just have a few machines in there place and some version of all of these. This makes for a very different Pinball climate for today and into the future. Yeah parts will go out of stock ( I remember just after y2k when you couldn't find parts and machines were robbed for their boards and such) But if there is a demand, other manufacturers produce replacements.

Damn, You beat me by 5yrs!
