A resin playfield is a big innovation as it won't dimple and it lends itself to multiple surface types. They don't need to worry about whether 8 ply or 12 ply walnut is good enough and whether their source for blanks is consistent. A flat playfield could include an area with raised mounds and craters like the moon's surface.
Other possible design elements - use air to move the ball via suctioning instead of a vertical mounted magnet. I'd like to see magnets deployed in place of all coils, vuks, flippers and slingshots. Doing that and swapping arm and rollover switches with optos would kill their need for the common playfield parts used today. Ok maybe keep the flippers,but everything else has got to go. Poured material is probably easier to embed and attach wire forms and ramps to also. I hope they add a loop ramp and corkscrew ramp to their standard repertoire and that they raise playfield glass height to allow balls to be launched from end of pf to the other. Could we see a catapult launch the ball 50 inches? I'm serious, can we see a catapult launch the ball 50 inches and a magnet grab it, please?
All of these would combine to simplify DR's manufacturing process and Operators would see lower operating cost, minimum maintenance and games that work. But innovation costs more money than the traditional way to do things until you implement in volume. For that reason DR won't be producing many $3.5k games. But if their pins are fun and worth the cost, they can meet their objectives and maybe they will succeed. What other innovations could DR's pinball future hold?
