I've only been in the industry a few years, but one thing I have learned is there is a lot of great ideas, that at the end of the day don't make it into a machine because the value is just not there. Do you want to spend $30 of your BOM to put a color diagram on the underside of the playfield? So, we then have a choice, we can have a drop down target mech or we can swap it out for a stand-up target so we can have a color diagram on the underside of the playfield. Assuming we do a good job building the game, few owners would have any need for that diagram on the underside -- so, I'll take the drop-down mech (preferably with a trip coil). There are dozens of lively (e.g. heated, loud, passionate) discussions and tough decisions on every machine about what to include and where to spend the BOM, and I'm sure that has been the case for pretty much the entire existence of pinball.
Now if BOM and sales price point don't matter, then a lot of this stuff is great. There is a not a design team in pinball who would not kill to have an unlimited BOM. In addition, a lot of what is here has either been done in the past or talked about in the past, but for the reasons already stated was removed or never added.
I think the touch pad display has a lot of potential, whether around game set up, high score entry, or in game selections, as sometimes two or three buttons is not enough. I would still want a physical button for things like magnet activation. As a programmer, having a 'keyboard' built it could certainly have value at times. However, there is nothing more important on a game than the lockdown bar and the flipper buttons. Those are your physical connection to the machine, if you mess with those, you sure has heck better get it right. We saw a game come out with a plastic lockdown bar and 'different' flipper buttons, and we know what players thought of that after playing it. Obviously none of us have touched this, but it certainly does not look comfortable or suitable for serious active game play. But until I touch it, hard to really know.
While The DMD was a great innovation for pinball, as it allowed for more complex rules as you could now communicate to the player more effectively (which we first saw with alphanumeric and that is why we got games like Diner and Taxi, as rules could now be more complex (also thanks to bigger processors/memory for voice calls, etc.). At the same time, and I know I am in the minority on this, I am not a big fan of the LCD in pinball. While it was natural evolution and they look great for spectators, and you can communicate a bit better to the player, and it adds a lot of eye candy, it also adds a HUGE expense to the development of a game, resulting in higher prices and not sure the value add is worth the higher cost. And you have to wonder what is being taken out of games to cover the cost of the display development. But the market place now expects it and that is one reason why games have less and/or prices have gone up. Now this Touch Bar adds another display that needs content. Obviously not as much as the main display (more like the secondary displays used on some games), but no matter what, that does not come for free.
As I said above, if BOM and sales price point don't matter . . .
