It's not really a review. It's just a hands-on description of the hardware. These non-reviews just confirm that Nikon wasn't telling lies in its marketing literature for the product. These non-reviews also attract traffic to the web pages on which they appear, which in turn drives ad clicks. The information in the hands-on hardware description is almost identical to about fifty identical 'reviews' on other sites competing just as hard for traffic.
ADDED . . . there won't be any proper/real reviews until photographers have had D800 bodies in their hands for at least a couple of weeks. Since the cameras aren't even landing for another 10 days or so, in-depth reviews are unlikely to appear before they land.
PopPhoto, DPReview and few other reviewers might have final production units in review right now if Nikon was actually able to nail its pre-production run for that purpose. We'll soon find out. Until the first public shipment lands, all review information on production units is embargoed by Nikon and its regional distributors. That's the way it works.
ADDED (again): A so-called review of a camera with which the reviewer is not allowed to make photos is not a review. It's marketing.
