Pixel information IS more accurate and is NOT interpolated.

Not if they have permanent color filters in front of the CCD.

Well, the sensor yes, but the camera no.

For single shot sensors, yes...

For B&W, with a 4 shot device, you could get true resolution with a single
shot (using a ND filter, just like the Leafscan does ;-), true...you do not
need 4 shots...depending on how the back was designed, and if it included an
ND filter.
