Honestly, for a landscape photographer and many others, the left AF point (out of 51) is not that big a deal. Especially if what you really want is resolution with a nice manual focus lens. Or by using contrast detect via live view. Of course we would like things perfect, but on the other hand for $2,500 or so it's killer. For other photographers, it may be a deal breaker.
I assume resales of the D600 are now doomed also due to the dirty sensor issue.
