@D70, I think the chances are excellent that your camera will be fine. Thom Hogan reported on Jul 26 that in a recent survey of dealers, it appeared as if they were no longer finding left focus problems. I have had my D800E for about a month and it tested fine.
Whether or not they are talking about it, Nikon has been aware of the problem for awhile. They know the fix and they know the problem. I think that it is extremely unlikely that Nikon would knowingly produce cameras with this problem once they determined the problem was real.
My understanding is that the problem was the result of a calibration issue with a machine that is used to determine a set of software parameters necessary to match the AF sensor to the body assembly. Once the problem was known, the fix should have been straightforward. Not so easy is re-calibrating the bodies that are now in the hands of consumers.
My feeling is that the manufacturing issue has been eliminated, and now Nikon is trying to figure out how to handle those units which have the problem.
I think the camera you purchase will be fine.
