I had some strange things with PSCS3 ACR with images taken today with the M3. I uploaded >80 images. When I looked at them in bridge, many would not come into focus. Checking the open with, Camera RAW was not an option. There were others that worked normally.
After playing around for an hour or two I fortunately still had the originals on the card. I opened a new folder and uploaded them again. This time everything worked fine. I have no idea why the first set had problems
Welp, FINALLY got my 1D mk III today. Lots to learn.
Of all the things new on the camera, one of them that I had initially discounted as being useful turned out to impress me a great deal - live view. I could zoom in to 10x, manually focus on tiny detail, even at f/1.4, and blam, perfect focus in the shot. This is going to help me a lot with detail shots at weddings where I want to use narrow depth of field to best advantage.
I took a few requisite test shots tonight. Granted, not super super scientific, but here is the setup:
50mm f/1.4. Same lens used on both a 1D mk iii, and a 5D. Photos taken at night, one single incandescent bulb on in the next room, a single candle next to the subject I photographed. Photos were taken handheld. Photos developed in C1Pro 3.7.7, only adjustment made was white balance, which was set to the same value for 1D and 5D shots. Photos then cropped in Photoshop CS2. Focus in all cases was on the highlight at the top right of the eye on the right of the toy.

I think the resolution advantage of the 5D shows a bit here, giving it a perceptably lower visible noise amount.
That said, the 5D would only focus (in this situation) on a highlight. I couldn't get it to achieve focus anywhere else at all. The 1D would focus -*ANYWHERE*- without issue. That impressed the hell out of me.
Based on what I saw in testing the 5D and 1D, I definitely think the same is true of the 1D mark iii. The same exposure settings worked to achieve the same exposure at ISO 3200. And halving the exposure time while doubling the ISO to 6400 still achieved equivalent exposure. So yes, I believe the 1D mk iii has the same ISO ratings as the 5D.
Now whether that is 1/3 stop faster than Nikon, I have no clue.

Maybe it is just me but the 5D shot seems to have considerably less noise.
I have both cameras. At 3200, in real world use with complex objects the DIII images look normal with some noise, while the 5D images at that speed look somewhat processed. Peering at solid color objects and featureless shadows is not the way to compare cameras.
Tonal transitions going to black may look noisier in the DIII at 100% pixels, but in print it's actually expressing the change correctly.

Thanks for the valuable clarification, I appreciate the feedbak.
Someone on another forum asked how the files dealt with being pushed in RAW processing. I went ahead and did so, and was rather surprised at the results. Bear in mind, this is perhaps more of an example of C1Pro 3.7.7 than the cameras themselves.

A few suggestions for comparing the 5D/1DmkIII high ISO:
It may help to shot a more detailed subject. Shoot in manual mode so that you get the same exposure on the subject. You are shooting at 1/25s with a 50mm lens. You may need a tripod for this type of test.
Also, in-camera sharpening should be off for both cameras. No tonal/color correction/sharpening should be added to the files. Try saving the files with low compression (JPEG 10).
I shot in manual mode to achieve the same exposure on the subject, often shoot sharp photos at 1/15th on 50mm, so I don't see that as a problem. I shot in RAW so that there wouldn't be any issue with in camera sharpening, and I saved them with low compression (JPEG 8).
I did apply precisely the same white balance setting to both cameras, however, and I truly don't see that as a problem.
I will try to use a more detailed test subject for my next set of tests, however.
Mine seems to be less responsive in AF than my 30D (meaning my 30D focuses faster). I've been playing with the two back and forth all morning, as I really don't want to send it back, because I have no idea when I'll get the replacement, but this isn't right. I noticed it last night. Bummer.
"The data in the tables below was derived by timing how long it took the Canon EOS-1D Mark II N to write out 16 Large (Quality 8) JPEG and 16 RAW .CR2 photos to the card. Timing commenced when the camera's card status light illuminated, and stopped when the light went out. Each test cycle was performed 3 times (if the card's capacity allowed for that) to ensure accurate results. All cards were first secure erased, then formatted in the camera (except for larger-than-2GB SD cards, which won't work in this camera unless they're formatted on a computer), prior to testing. The same test scene was photographed, under the same illumination, for all tests. The identical camera settings and lens were also used for all tests."
According to Mr Galbraith!
I will be doing exactly the same thing when my 4gb SD HC card arrives tomorrow!
I got a spare battery at a local LA store (Bel Aire Camera). It was $170 + tax! However it's a Li-Ion battery and since there are tales of Li-Fires I wanted a Canon battery.
