Sensor size makes no difference in image quality until you reach the diffraction limit. It makes no difference whatsoever in light gathering capability, that is determined entirely by the lens system.
Also, CCD sensors are widely used because they're cheap and easy to make, and more development has been done with them. A CMOS sensor such as this may have numerous advantages.
The Sensor size has much to do about image quality. The tiny 1/18" sensors in most P&S's have far less DR, High ISO performance (noise), and overall resolution than the larger DSLR sensors of 23-24mm (cropped), or the Full Frame (35mm film size) CMOS sensors on Canon's 5D and the 1DsMark II. Difraction only comes in at extremely tight apertures (usually F16 and above), and has more to do with the lens than the sensors. This new samsung chip is most likely going to be used for camera phones and other handheld devises and probably some P&S's. Unless it has some "revolutionary" new kind of technology that can increase DR, IQ and still maintain high ISO performance, I don't think you'll be seing then in any pro or advanced prosumer DSLR's anytime soon...
As others have stated, you're wrong on this point. The larger the sensor, the most light it can physically take in, it's just physics. You can focus all the light you want on a tiny sensor, but then each CCD is seeing pretty much the same thing.
