Now imagine such a new sensor with a little less pixels e.g. 10MP.
What a low light wonder would that be?

Well, since there's no such camera, the next best thing is to resize the images down... which pretty much has the same effect. Also because of the inefficiency of Bayer sensors, the larger image that's resized down will have more information (real resolution, not pixel dimensions) than the image that came from a less-MP sensor, even if they both have the exact pixel dimensions. Which means, for example, you can resize a 16MP image from a 16MP sensor down to less than 10MPs and still end up having the same detail as a 10MP image that came from a 10MP sensor.
Oh, and Nikon is known to perform NR on the Raw files...

It's sad how everyone's so caught up with noise figures these days but no one bothers to measure how much detail they're getting... especially when the sensors are so different.
