Everyone has different preferences - and yes better ISO performance is great. Here are some stats from my Lightroom database that I find interesting:
Number of images: 38,632Number cropped images: 34,202Number images with noise reduction applied: 94Number cropped images with more than 25% removed: 11,661
From my stats: high ISO is nice to have. Room to crop an image and still have some pixels left is essential. I am very happy to see cameras I can afford move in this direction.
The D800 will match or exceed the ISO performance of my D7000. I will take more pixels for extra cropping room over ISO improvements that are always eclipsed by the next gen camera anyway.
Craig1959: Many are claiming the D800 is creating a new round of unwanted pixel wars. How can that be? The D800 has roughly the same pixel density as the D7000. I don't remember anyone suggesting the D7000 had an excessive number of pixels. The D800 is simply a D7000 upscaled to FX.
After reading this review, I realize that the D800 is an "FX camera with a full resolution D7000 inside it". I have a 10.5 mm DX fisheye and 10-24mm DX wide-angle. Surprise: They will work the same on the D800 as my D7000. My 24-70 mm and 70-200 mm FX lenses will finally work as they should in FX with the option of cropping in POST down to D7000 size. I am selling my D7000 and buying a D800 to get two cameras in one. My DX lenses finally work acceptably on an FX camera and I can my use my FX lenses to their full potential. I believe the D800 is currently the only camera that can make this claim. I'm in.

docfink: I gotta finally shout this out to all the whiney, geeky, pixel-peeping ninnies out there who love to tout one brand over another and make these photo forums the MOST ANNOYING AND UNINFORMATIVE areas for discourse on the net:
The D800 is sweet. The 5D3 will kick ass too. Your lenses will work beautifully on the D800 and the focus will be sharp--even when wide open. Geeks and pixel peepers will be annoyed by certain things, but clients and family will think you're the second coming of Ansel Adams. Got that?
Again, as someone who has several other hobbies for which I frequent Internet Forums, these photo forums ARE AN EMBARRASSMENT and a turnoff to those who actually want to learn. It's hard to filter out the useful with all the whiney crap posted in between. Police yourselves, please.
Let's get a moderator here to delete annoying comments that have nothing to do with the original post or go off topic.
Seriously--consider what I'm saying before you cry and post junk.
Across the web, it would be nice to have a "pedantic" button next to the "like" button.
These bombastic comments have one upside: People can see they are smarter than the statistically average contributor.
Alejandro del Pielago: Very few night shots -almost nothing. Everybody desires that samples...
A safe assumption: With the same pixel density as a D7000 and 1 year newer firmware, high ISO performance will be marginally better than the D7000. Given these parameters, I can't see Nikon releasing a camera with lower performance. It will be interesting to compare high ISO on a D7000 and D800 with a DX lens too.
