The 18mp crop sensor is about 1 stop better than the 50d in noise, 5dII about 1 stop better than that and 5dIII 2 stops better than that.

While I grant that the 5D3 is a better camera than either the 5D2 or the 7D (an 18MP crop camera) it does not seem to me that the 5D3 is 2 stops better than the 5D2. In fact examining raw images from the 7D, the 5D2 and the 5D3 would seem to indicate that there is perhaps a 1/2 stop difference between the 7D and the 5D2 and one more stop between the 5D3 and the 5D2.

Some of the threads comparing the 5D2 and the 5D3 put the difference at 1/2 to 2/3 of a stop. I grant you that the 5D3 ISO range goes 2 stops higher than the 5D2 but the images are not comparable. The 5D3 is, at most, 1 stop better if the images and comparisons are to be believed.
