more importantly what will the USEABLE iso range be...
i hope 12800 usaeable maybe 25k native with 50k and 100k extensions?

The rumor on NL is 25600. That sounds about right based on the Canon method of rating ISO. If the sensor is one stop better in raw than the 5D MK II, that would be very good. We are at the point where we only get incremental improvements in high ISO noise.
The raw images for the D800 look pretty good at IS)3200, and with NR and a loss of detail, they will be usable at 6400. I'm hoping for one stop better.

I just hope its pretty close to the 1dmk4 if not better.... I shoot alot of concerts, weddings, and sports.... This camera sounds like the holy grail... (to me at least)
useable iso 6400-12800 should be standard.

The 5D MK II is already better at high ISO than the 1D MK IV, so thats a safe bet. Full frame has a considerable advantage over crop sensors in low light.

Lower noise at high ISO, not max ISO - at 6400 for instance, 5D mk2 has less noise than 1D mk4 (if I am not mistaken, the difference is half a stop or so)

Sports worthy? As in 7-8 FPS? And FF? You are asking for a 3500-4500 dollar camera.

Have you looked at image samples?? 5D MK II is obviously better at high ISO's.
You can also check DXO's measurements of the sensor low light properties.
The difference in the two is the in-camera jpeg processing that the 1D can do with its dual processors, so jpeg images look pretty good, but if you use raw, the 5D MK II is much better due to the fact that the images get the same high level of processing.
The ISO setting on a camera is no indication of relative performance.
Even some point and shoot cameras can sometimes be set to ISO 6400, but that does not make them equal to a 5D MK II.

I can second that. I used to shoot a Contax 139 Quartz back in the day (1982) using the Kodak Tri-X pushed to 3200 ASA...those were the days...
Looking forward to the new 5D while I don't hesitate to shoot my 30D at ISO 3200 using street lanterns as long as I can exposure to the right with 50/1.4 wide open. Compared to this quality 12800 or even 25600 will look great on the new cam... 8)

The DXO definition is as good as anything, and, at least it can be measured. Ratings from individuals based on their eyesight may vary all over the map. http://www.dxomark.com/index.php/About/Sensor-scores/Use-Case-Scores
"Sports & action photography: Low-Light ISO
Unlike the two previous scenarios in which light is either generous (studio) or stability is assured (landscape), photojournalists and action photographers often struggle with low available light and high motion. Achieving usable image quality is often difficult when pushing ISO.
When shooting a moving scene such as a sports event, action photographers’ primary objective is to freeze the motion, giving priority to short exposure time. To compensate for the lack of exposure, they have to increase the ISO setting, which means the SNR will decrease. How far can they go while keeping decent quality? Our low-light ISO metric will tell them.
The SNR indicates how much noise is present in an image compared to the actual information (signal). The higher the SNR value, the better the image looks, because details aren't drowned by noise. SNR strength is given in dB, which is a logarithmic scale: an increase of 6 dB corresponds to doubling the SNR, which equates to half the noise for the same signal.
An SNR value of 30dB means excellent image quality. Thus low-light ISO is the highest ISO setting for a camera that allows it to achieve an SNR of 30dB while keeping a good dynamic range of 9 EVs and a color depth of 18bits.
A difference in low-light ISO of 25% represents 1/3 EV and is only slightly noticeable.
As cameras improve, low-light ISO will continuously increase, making this scale open"

@Mt Spokane being a non-anglo and non-tech I only get a faint idea concerning your insightful explanation. Could you please tell me what this means for the rumored high ISOs of the new 5D?
Up to which setting will the 30dB work for excellent quality? 6400? or does that mean 100-25600? sorry. I know it's gonna be a hard job for you but thanks in advance. or as I am currently shooting a 30D you might use the H 3200 as a reference in comparison to a new 5D. 1600 and good light is fine. 3200 is quite usable with fast glass 50 1.4 and wide open, exposing to the right. A type of digital robert frank "the americans" style ;-) which I like very much as I am veteran from the filmdays
Cheers, Pedro
