I've heard from three dealers in the past two days who've been checking newly received D800 shipments for focus problems. Combined, they received a bit over 100 bodies, and if I'm adding up the numbers right, they sampled about a quarter of those overall with some basic focus testing. None showed the left sensor alignment problem.
That's a good sign, and based upon what I know about when the problem was detected and product shipments, that's what I expected to hear. Unfortunately, with Nikon's continued silence on this issue, that's not a large enough or random enough sample for me to say that the coast is clear. Therefore I can't change my recommendation back yet.
I'm in the midst of my summer travel and product testing schedule at the moment, so I probably won't be making a further statement about this until I get back to the office in early August and can double check and broaden my sources of information.
I've never doubted that Nikon would fix this problem once it was discovered. It's really the uncertainty that Nikon has promulgated and the lack of clear and specific response that has been the problem. This is an example of a company in denial about the level of their customer service and communications. Most Nikon users are quite loyal. But that loyalty gets strained when Nikon goes silent instead of acknowledging an issue.
The proper response would have been: "(1) we made some D800 cameras that have incorrect data in them; (2) we don't know the serial numbers of affected units; (3) here's a simple way to test to see if your camera has the problem; (4) if yours does, here's how to arrange to have it promptly reprogrammed at no charge; and (5) all units shipped after July 1 are free of this problem and don't need to be tested. We apologize for the inconvenience."
