Wendell R. Breland 12 bit, 4:2:2 because there are many more steps between black and white + Deep color. Bit depth determines number of steps, X:X:X determines color to luminance sample ratio.

IMO, there is little chance that we will see more than 8 bit, 4:2:0 in the near future for home use. As it stands H.265 (HEVC) will need extensions ratified in order to accommodate anything greater than 8 bit, 4:2:0.

ADD: Also, the more bits you have the greater the S/N ratio. 8 bit ≈ 48 dB, 10 bit ≈ 60 dB, 12 bit ≈ 72 dB. In the real world these numbers will be different but you get the jest of it.

Sharp's colour spacing is unique.

Sharp's colour gamut produces array of technicolor and spectrum ranged sampling. However with subsampling the pigments can stray off and CYB is not the same.
