Nikon Patent 7,138,663 describes a microlens placed over three photoreceptors. By using dichroic mirrors, each wavelength of light (red, blue, green) is directed to a specific color receptor. This reduces the gap between photoreceptors, eliminates the need for an anti-aliasing filter.
According to Nikon Rumors, the D800 will come in two flavors. We can only guess that they may be optimized along the lines of the D3x and D3s. That is, one will pack as many pixels as possible (36.3 megapixels) and be the choice for studio and lanscape, while the other will give superior low light capabilities (50-25,600 ISO) and outstanding dynamic range for amazing sports and wildlife photography.
One possibility is a model without an anti-aliasing filter. Most consumer digital cameras feature an optical filter in front of the image sensor. Anti-aliasing filters reduce sharpness, but remove color artifacts (jagged edges) and Morie patterns. Some image sensors, such as the Sigma Foveon 3X, have three separate layers (one for each color) and eliminate the need for an anti-aliasing filter.
Digicame Info has confirmed the Nikon D700 successor will be called the Nikon D800.

Further information suggests that the D3S successor (the D4) will be released in February 2012. The camera will provide 18 megapixels at 10 to 11 frames per second. The AF system will also be improved. The D3X will likely disappear without a successor.
Nikon Rumors has reporting receiving some additional info and gives a 99% probability to the name “D800″ and the sensor size of 36MP.
