and that those sensors would be maybe ?? superccd sensors ??? even bumping up resolution on super ccd sensors have their drawbacks, improvements sure have been made to sensors and the way they gather light, but a lot of it has been with the in camera noise removal. superccd sensors which simply have a more efficient shape and configuration of photosites can pick up more of certain wavelengths but as a drawback they start getting color artifacts even at good light conditions. (aka superccd artifacting). another type of sensor; foveon x3 is a direct or color image sensor without a color array like bayer filter (which is used in almost all cameras except sigma dlsr's) but again they are as prone as bayer filters or superccd sensors to photosite size and its light gathering capacity.

again some improvements have been made to almost all sensors both bayer or foveon x3 or superccd's but a lot of it has been made also on the software side with noise removal etc. still photosite size is the major consideration while making a sensor.
