I am rather excited for the new Foveon sensor cameras actually. While there are only 4.7M specific pixel sites on the sensor, each one contains 3 separate silicon sensors, allowing for the gathering of full RGB information at each photosite. This will give more "true" color theoretically when compared to a Bayer pattern sensor which only collects one color and approximates using its surroundings.


Though the total pixel count is only 4.7MP in actuality, these sensors are often compared to 9-10MP cameras due to their enhanced image quality, and lack of necessary demosaicing.


I am also interested to see how low light sensitivity plays out, since the individual light gathering sites are significantly larger than on many competing CMOS sensors.


I am not jumping to buy a Foveon sensor quite yet, but I can't say that I think they are a weak concept.
