What I took from my question to Austin (Horses Mouth, about a week ago) is
that these one shot cameras interpolate color, not detail.

As you say "A red sensor produces, via interpolation an RGB pixel." That is
true for color mode, but as far as detail is concerned it doesn't care if
it's captured by an R, G, or B, sensor, and it only takes one color of
information to make detail. The depth of tone of that pixel may be differ
depending on which sensor records it, but a true pixel worth of detail
(let's call it a gray pixel) will be recorded.

Thus, for grayscale, the number of sensors the camera has IS the amount of
detail it records (raw) - no interpolation is necessary.
