The luminance noise is finely grained and seems easy to remove in LR4. Color noise a non-issue with LR4.
That ISO 12.800 photo does looks promising, but there isn't much fine detail in the picture so it is difficult to evaluate the IQ. Give me a portrait @ 12.800 in raw and I could serve a judgment mush easier.
Here's a very rough 1DX vs D4 comp. Both processed in ACR 6.7RC, all defaults, NR off for both chrominance and luminance. The D4 image is from imaging resource and has a 2000 degree higher WB, giving the D4 an unfair advantage but it's all we have

OK, I have now checked the second raw-set in Lightroom and is quite happy with the results.
The impressive part for me is that you don't absolutely have to apply Luminance noise reduction at ISO 12.800. The luminance noise is very nice. Just a bit af L NR - like 15 - cleans the noise great.
Banding/pattern noise @ ISO 250. There is a touch of that in the shadows, but it is somewhat random and not really that strong IMHO. It is not Sony EXMOR clean, but way better than 5D Mark II. Not a big concern for me at this point, but we obviously only have one shot to go by. It might even be better in the final production camera, if they didn't calibrate the demo camera 100%.

I believe I read somewhere 1Dx supposedly offers 1-1.5 stop difference. I don't see it at all!
I spoke to Canon. They said RAW noise improvement over the 5d3 was about 1/2 stop.
People keep quoting JPEG improvements which is where all of the unlikely differences are coming from. Physics simply wouldn't allow a 1.5 stop increase unless Canon had found something unbelievable..
