I remember when Kodak patented the similar color array. I always wondered why it didn't come to market sooner. I'm not sure what difference it will really make - it will let the camera see some extra detail in shadows but only at the resolution of the white pixels, and without the color information.
I haven't given much thought to how the demosaic algorithms could use this to make less noisy images, since the amount of light collected by the other pixels won't change - and consequently the noise in three color channels the RAW converter uses will still be the same. It's possible that it's mainly mentioned as a cell phone application, because that's all it's good for; But I have hope too - maybe a super high res sensor would have enough white pixels that you could use the detail they capture to do better noise reduction on the other channels.

....and what impact could this have on a sensor for black and white photos only? Or is that a stupid question?
