I'd say either a Kodak sensor or Canikon. There really is no better color fidelity obtained when using a CCD. As to the Foveon, I still chuckle when I hear about color fidelity from Sigmas. Let's get one thing clear....the Foveon has the WORST color going. Period. Check an iso 800 or 1600 image from the SD1 and come back and tell us about color. It's a joke. If Leica went Foveon (and I don't think they're that stupid), I wouldn't touch anything from Leica again.
And Animefx, the M8 does not have great dynamic range. In fact, it's rather mediocre. Today's CMOS sensor wipe the floor with these old CCD chips that are ridulled with noise and weak DR. Cameras like the Pentax K5, Nikon D700, Nikon D7000, Nikon D3x, etc, etc, leave the M8 way behind in noise and DR.
We don't need CCD. We definitely don't need the poor color and horrendous aliasing and oversharpend look of Foveon.
