Not a lot of D600 failure reports

I have used mine for 2 weeks and not a problem. I am going to give it a run this weekend on my wedding. will be curious on the low light focus and how it perform in low light. So far a gem. Yet I am still curious if it is the end of the D700. We know that the D800 isn't the replacement. I wonder how many shooters out there would buy a D700X with the 24mg sensor as the D600, beef up some other items and remain it as a still camera no video. I am sure there will be alot of people want this camera. The only thing it could kill D600 sales. So it's in between the D800 and D600
