Cowseye said:My bet is still on the MP and F/8 AF point from D800. Plus the $599 USD savings
totally love the D800... but the batt grip price is kinda turning me off... batt grip is a must for me

How much?
I think 5diii has better ISO as they REALLY emphasize their 2 stops improvement. If it is really 2 stops better than 5dii, I think should be really good.
Hopefully nikon still win on DR because of the improved sony sensor.
61 AF pts from Canon might not mean better faster focusing than Nikon. If the 5D3 still uses the old 5D1 AF system which the 5D2 also uses, you'd soon see alot of users complaining in the forums about its focusing just like what happened to 5D2. Nikon AF system not only focuses faster, but also accurate and able to focus in very low light.
Wait till all the cams are released then see how they fare...
The EOS 5D Mark III utilises the same 61-point wide-area AF system as the flagship EOS-1D X, providing exceptional sensitivity, precision and speed. One of the most advanced AF systems currently available, it features an impressive 41 cross-type points and five dual cross-type points, providing unsurpassed accuracy across the frame. The customisable AF pre-sets introduced in the EOS-1D X are also available, helping the capture of traditionally challenging subjects, and providing additional reliability in ituations where subject movement can be unpredictable.
As before, with lenses of f/5.6 or faster, 15 of its 51 AF points act as cross-type: sensitive to both horizontal and vertical detail. The 9 central focus points will continue as cross type when used with lenses with a maximum aperture of between f/5.6 and f/8. The D800's central AF point will still operate as a cross-type point with lens or lens/converter combinations with a maximum aperture of f/8. In addition, 10 AF points retain horizontal sensitivity at this aperture. In the diagram above, cross-type sensors are indicated in orange.
think we should look at the hands-on prereview take on the AF system rather than Canon's PR dept's write-up... taken from Canon EOS 5D Mark III Hands-on Preview: Digital Photography Review:Taken from Canon announces EOS 5D Mark III 22MP full-frame DSLR: Digital Photography Review
The EOS 5D Mark III utilises the same 61-point wide-area AF system as the flagship EOS-1D X, providing exceptional sensitivity, precision and speed.

The customisable AF pre-sets introduced in the EOS-1D X are also available, helping the capture of traditionally challenging subjects, and providing additional reliability in ituations where subject movement can be unpredictable.
The biggest single upgrade on the 5D III is its autofocus system, and it's the area that most needed it. The original 5D's 9-point AF system seemed a little under-specced when it was launched, so its reappearance in the Mark II was a considerable disappointment, especially when the 7D arrived a year later with a much more sophisticated 19-point setup. The 5D III's AF eclipses both, gaining the 61-point AF sensor from the company's flagship 1D X.
It's not the entire 1D X AF system - because the 5D III doesn't have the 1D X's 100,000 pixel metering sensor to gain tracking information from, nor a dedicated Digic 4 processor to make sense of it all. However, even without them, it's still one of the most comprehensive AF systems on the market and, most importantly, brings the camera much closer to the level of contemporary Nikons.
