How about the noise profile?

HK, did you get a chance to compare the look of the noise?  Whether JPG or RAW, I find judging the look of the noise to be much more important than the amount of it, and how the NR deals with it.  I always strongly favored the fine-grained, uniform, luminance noise profile that the 16MP APS-C sensor produces, and did have a bit of a problem with the chunkier, more chroma, blotchier type noise that the 24MP APS-C sensor produces.  When it came to noise reduction in camera, the blotchier and more chroma noise is harder to remove cleanly, which I think is why there are often so many complaints about the A77's high ISO look in JPG.  From what little I've found, it looks like the A99 doesn't produce as much chroma, but that's at middling ISOs where the larger sensor alone could help - once pushed to the extreme ISOs like 12800+, does the noise stay fairly low in chroma, and the noise pattern fairly uniform and non-blotchy as it does on the 16MP sensor, or does it start to get patchier or blotchier or introduce more chroma?

Thank you.
