Well, it's official - take a look at the Nikon website and they have decided that the D600 heads up their DSLR 'Consumer' range of products. Nikon does not categorise it as being one of their range of 'Professional' DSLRs. Interestingly, Wikipedia lists the D600 as the D300 replacement, which goes to show how suspect the information on there can be.
The D300S already sits firmly at the bottom of the Nikon professional range. Given that the D300, as good as it is, is now so woefully ancient compared to the newer DSLRs in both ranges (D7000, D3100, D3200, D600, D800, D4), common sense would suggest that Nikon really will have to do something with the D300 soon. That is, either bring out a D400 model to replace it, or simply drop it from the range.
I was recently talking to the sales manager at my local large branch of a chain of UK photographic stores. He told me without hesitation that he has not sold a D300S for over 3 months and that head office has informed him to shift any remaining stock back to central distribution so that they can send them out to other stores when required to service the very small demand for them.
It looks like the writing is on the wall for the D300. That makes me pleased - not because there is anything wrong with the D300, but because I am one of the large worldwide group of enthusiast photographers who have been waiting for a D400 for over 3 years now.
Nikon has a habit of doing nothing for long periods in terms of product release. Then it suddenly wakes from its slumber to release many new models. With the D4, D3200 and D600 releases following this pattern, I am now living in hope that Nikon will finally release the D400 very soon.
