Quoted from _litz:At some point in the future, there will be 128x32 color LED panels, which'll have the same form factor as the original plasma ... at that point, presumably the colorDMD product will shift over to using the newer technology, and it'll be applicable to games like SC or CV.
Quoted from Aurich:I doubt it honestly. Too expensive and specialized for there to ever be a need. Pinball will shift away from LED panels and that will be that.
Not to mention that RGB LEDs are larger in size than standard single color LEDs resulting in a much larger screen than will actually fit any machine. Also the spaces between each RGB LED are much larger as well creating a somewhat blurred effect.
Then of course you have to drive them which would require the use of a CPLD or FPGA as a conventional micro-controller simply won't be fast enough.
