The 100% crop of eye @ ISO 800 1/80s has impressive details in it. If similar IQ becomes available in 5DIII/X @ ~3k, i would seriously consider preordering a camera for the first time ever.
In the top image, it looks like has good DR too (especially if thats a JPEG straight out of camera)
Agreed, I noticed that also. While I am not going to be buying 1DX, I am sincerely hoping that 5DIII/X is not a megapixel monster but rather shares the same sensor with the 1DX w/ lower FPS. As tempting as the megapixels in D800 are, I am perfectly content with the 21 of 5DII and a lower MP for higher DR & ISO performance on the next release :-)
