I have gone through all the raw files and this is by far the cleanest Canon camera I've seen in a long time regarding shadow noise

I didn't measure the absolute strength of the vertical banding, but it can be seen.

The high ISO is of course, similar to or even slightly better than the D4. The 1Dx does not seem to become "ISO-less" until a very high ISO; the 12800 RAW has only about 2.7x the read noise of the 3200, rather than 4x normally expected (unless the metered gray point is different at these two ISOs; hard to tell with completely different shots).
