D600/D610 Swaps The Real Issue?
Glad to see DPReview query Nikon. But I think they are missing the real implication of all this. Even if the OEMs can't agree on a "watchdog" clearinghouse, I think it's time for each OEM to issue the equivalent of NHTSA Technical Service Bulletins (TSBs). (National Highway Traffic Safety Administration in the US.)
These are situations where short of a recall threshold, the OEM acknowledges an issue and will repair the car under warranty when the owner brings the issue up to the manufacturer's service department at a dealership (i.e. Authorized Service Center). At what some cameras now cost, it's time for such an approach in the camera industry, I believe.
Dust and oil on sensors; faulty AF; lens error on point and shots; printers with abnormal incidence of print head failures; etc.
