Does multi layer mean foveon like or does it mean something else? Seems there are other possibilities with additional filters.
I am a foveon user and can say for some applications it is exceptional and for others terrible. It would be fantastic to see another company push this type of technology beyond its current state. I hope Canon is this company. Maybe Canon does not need to make this type of sensor to be good at everything, just good at specific things. Look at Sony A7r and A7s. Both sell well, yet both are good at different tasks.
Really looking forward to seeing companies take image quality more seriously, by this I mean, eliminating IQ destroying Interpolation and bayer colour filters.
