It is just for fun. Anyway, it is more interesting to be seeing living colours than a colour chart. You cannot see the tonal colours or textual of petals in colour charts.
I choose to see it differently. Kodak is still in Leica ME which means it is going to be supported for x years. There are also the medium format digital backs. I think someone will do something with those sensors. I am sure you also know how popular the Sigma DP series is. I think Foveon sensor will be big if Sigma can make a small DSLR. Even if they are destined to fail eventually, it would be a pity for someone to not have taken their love ones in a different light, using these sensors that have its unique signature other than the sharp, high resolution, clean high ISO CMOS.
Ok, let's go back to Zeiss lenses....
