Well, no.  There are 6.3 million real SENSORS, not pixels.  A COLOR pixel,
as used in any imaging program, consists of ALL THREE COLOR COMPONENTS, red,
green AND blue, not just one of them.

It's somewhat the same as just taking a group of four of the Bayer pattern
sensors and calling them a pixel ;-)

They absolutely ARE interpolated.  It is a 6.3 megaSENSOR chip.  It
interpolates the 3M green, 1.5M blue and 1.5M red sensors and gives you a
6.3M pixel file, just as Darren said.
