Stern is doing great. However, the market is entering a classic oversaturated state. JJP, I own two and they're a nice change of pace from others. Not better, not worse...different. Loads of personality in those. American Pinball, very mysterious as to whether or not they're making it, probably depends on their backers $$$ Spooky are playing by themselves in their own sandbox and doing fine, thanks. Own an ACNC and it's tough but in a large collection like mine it's fantastic to have and one of my better machines. Deeproot, who knows? They are certainly blowing lots of smoke but have lots of dough and talent. Joker's wild with those guys.
If I'm Stern and I see this, I would be careful but confident. They might be releasing too many tables for a saturated market, but maybe the losses are part of their plan?
Probably time for them to innovate/change a little but stay with what they're doing/work their connections...
But I'm highly doubtful there's room for *all* these players to survive.
