Go to a club with the 5DIII one night, and a D800 another night, and see which one gets you more women. Be sure to take lots of sample images.

Personally I am not convinced about the DxO measurements - they dont pass the common sense tests
Why don't you start writing reviews by your own, Neuro? Seriously. I find your comments very useful.
We have heard that the D800 has wonderful metering must take the shots in green square mode
Yes absolutely more DR means a greater amount of perceptible detail from the shadows (noise floor) to the highlights (clipping headroom). You won't crush your blacks (lose shadow detail and/or have perceptible sensor noise) or blow out your highlights (e.g. lose the clouds in the sky) when you have more DR. And shooting RAW with lots of DR, exposure settings aren't as critical as a result, you will retain detail even with relatively poor metering.
The D800's photocells look to have very similar DR to the 5D3's, but the D800 has packed them more densely, and DR improves when reducing resolution, so the D800's advantage in MP will be felt in the noise performance of an uncropped but reduced resolution output. So if you are delivering 8MP JPEGs from RAW originals with the same per-pixel DR, the 36MP original will have better delivered performance than the 22MP one. At least that is how I understand the theory there.
Example: Let's say D800 has 14 stops and 5D3 12 stops. Using mild simplification, the D800 can represent the entire 14-bit range of [0,16383] and 5D3 only the range of [4,16383]. I'd assume the D800 now gets a significantly higher score in "objective" rating for DR, since after all, it has those two extra stops. But those extra stops are represented by values 0, 1, 2 and 3. Hardly a significant advantage, I'd say. Nor is it reason to moan that Canon have done nothing in 3,5 years since the 5D2 also had 12 stops.
I understand that the DR is 14 stops. My point is that the bottom stops are not usable in any practical situation since the quantization destroys any detail at that level. You can dither so that the average quantization error over the whole frame is zero, but still the local pixels have little to do with the actual frame you were trying to capture.
I doubt I will change to Nikon... too much invested in Canon equipment - however I also doubt I will buy the 5DmkIII. I am quite happy with the mkII right now and not seeing enough of an improvement to warrant moving up yet. Just thinking about what I would do for my next camera and why the Nikon is cheaper then the Canon....
I enjoy the troll posts because I can replace D800 with 5DmkII and D700 with 5DmkIII and find the priests of low light swapped places with the megapixel crusaders. It is fun to watch, and yup, goes for all the canon guys that are now the priests of the low light religion! Watch if canon makes a 30+MP camera and how suddenly, 22MP is too little and OMG how did we manage with that .
