Yes, Stern kept 90's style pinball alive. And put out some games with great code (thanks LFS and KEF).
But pinball is not relevant to the general public. The typical response from non-pinheads is "they still make those?"
At least WOZ looks newer with the LCD. And it pushed the color lighting out there as well.
Pinball collecting is bigger than ever, sure, and so is competitive pin.
The most healthy pin has ever been? Hardly.
Pin has made a comeback multiple times in the last with Space Shuttle, HS, TAF, etc.
It can do it again.
But until someone makes pins that teens and those in their 20s want to drop coin on, pin will largely be limited to collectors, shows/competitions, and locations run by pinheads.
