It seems Nikon has already quietly fixed the flaws that had caused the issue in the production line when the issue was first discovered and reported to them just a few days after D750 got into shooters\' hands. Nikon believes the best way to handle it is to just keep its mouth shot so it can quitely go away. At any way, Nikon can always dump those returned but fixed D750 bodies as refurbs at their wholesale price and still can come out unscathed financially.
