Quoted from rubberducks:
Either way, I'd be quite surprised if Stern didn't intend to amortise the per unit cost increase due to display content with the presumably significantly reduced DMD -> LCD cost.
Nobody knows what Stern paid for their DMDs. Probably a lot less than we got the AMH ones for. And remember Stern uses the better version of the LCD. So the hardware savings might not as as much as you think.
If you look at Alice Cooper the LCD is like a third what the AMH DMD cost....But! You need a single board computer to drive it, PROC, and an HDMI to LVDS converter board. And on top of that you have to create tons of content from scratch.
So for smaller companies with fewer games to amortize costs across the LCD is most certainly a landmine they've all happily chosen to step on.
