I know people out there have will opinions &/or informed speculation about this:
http://www.dpreview.com/news/0706/07061401kodakhighsens.asp The short version is that by replacing 1/2 of the sensor elements of a bayer pattern with panchromatic elements, Kodak claims a 1-2 stop boost in sensitivity: "This breakthrough advances an existing Kodak technology that has become a standard in digital imaging. Today, the design of almost all color image sensors is based on the "Bayer Pattern," an arrangement of red, green, and blue pixels that was first developed by Kodak Scientist Dr. Bryce Bayer in 1976. In this design, half of the pixels on the sensor are used to collect green light, with the remaining pixels split evenly between sensitivity to red and blue light. After exposure, software reconstructs a full color signal for each pixel in the final image. " Kodak's new proprietary technology builds on the existing Bayer Pattern by adding panchromatic, or "clear" pixels to the red, green, and blue pixels already on the sensor. Since these pixels are sensitive to all wavelengths of visible light, they collect a significantly higher proportion of the light striking the sensor. The remaining red, green, and blue pixels are then used to record the color information of the scene."
