If we could have anything near what WMS puts in slot machines these days it would be tremendous. Transmissive LCDs on the tables, for example. Imagine the upper clear layer of a transmissive LCD mapping specific shot vectors on the table. Inserts are no longer individual pieces, but displayed instead as graphics. You wouldn't need to take your eyes off the table to look up at mini modes on an LCD backbox or DMD, it would all happen right on the playfield.
OLED buttons can be made into OLED targets. The durable tech is already there in our local casinos. Targets could evolve on the fly, show completed hits, display video graphics. The whole game could be made wild with color. With flexible OLEDs, even ramps could be made to display video graphics.
