I think it'll depend on what Nikon does with the D600. I'm hoping it'll get replaced sooner rather than later with a better AF system so my hope would be around 2 years.
It is obvious how canon sees the camera, the 6D falls into the same CPS category as a 40D which should hopefully mean it'll be changed quicker. It would also be a reasonable upgrade if they specced it with a better AF system and could see the enthusiasts upgrade.
well, I have both the 6D and D600 and the D600 AF is not better in any area.
seriously , the D600 AF is the same old consumer AF of the D7000, which is very slow and unreliable.
you may be a one system user and do not know anything about the other side(Nikon), but you should know the D600/7000 AF was one of the worst AF systems ever made despite of its decent paper specs.
Nikon tends to give you great numbers on paper but it does not work in real life.
I wished my D600 had gotten the same AF from the D4 used in my D800E.
That said even the D4 AF is not as good as the 5D3 AF , and the for that AF , I may make complete switch to Canon after a couple of church event works over in this summer.
I still prefer UI of Nikon since I am very very very used to shooting D800/D700/D600 but now video and AF are becoming most important aspect of camera qualities, at least in my area of work.
the 6d AF on paper is poor , but in real life it is excellent at least the center point of it is very very sensitive and reliable , I think having even one very sensitive AF sensor is better than having useless 39 points that cannot focus in dim light.
honestly, the D600 is one of the most over rated and hyped cameras ever , it is not that good.
it has dust issue , LV issue , green cast issue and its weak plastic pop-up flash makes my PCE lenses useless(I really hate popup-crap , and never understand why Nikon has to put that crap in any Dxxx model?)
the 6D was harshly criticized when it was first announced but most of its actual users love it while many many D600 users having the infamous dust issue or AF issue.
so go Amazon and read some D600 horror stories and compared to EOS6D stories.
