I'm 47 and have loved pinball since the early 1970s. The only way I'm going to sell my pinball machines is when I'm dead. That being said I'm not sure if today's youth have that passion as I do. I would hope my son will continue to enjoy my pinball machines and playing pinball long after I am not around.
I think pinball will face some coming challenges years from now. I believe there will still be pinball in the future but probably not as big as it is today. Look at 40-50 years ago and compare it to the size today. Now go 40-50 years from today and think what the size of pinball will be.
