well i believe that you are never check on real life and only read on website. even you check on bnh store: http://www.bhphotovideo.com/c/buy/Digital-Cameras/ci/9811/N/4288586282 u can see that nikon D600 is 100usd more expensive that canon 6D. so do your homework or reality check
Well, your homework consists of finding a globe and trying to find the US. Got it (it might say "Center of the world" on your version)? Good. Then look at all the other countries, amazing, isn't it? Well, and Canon sells dlsr everywhere, that's why I quoted the € (that's "Euro") prices, and even if you don't care about that in an English-written forum there are always the Brits and the Ozzies who don't pay in US-$.
Well there are some Indians as well who don't pay in US$. We have to pay in Indian Rupees.
FWIW, the situation is much the same in India with the D600 is priced at INR 120,120 while the 6D is priced at INR 124,995. Translating into US$, a price difference of approximately US$ 82.
Well i am from indonesia(itson southeast asia in case u dont know). In my country canon 6D is rp.16.500.000 ($1650) and nikon 600D rp.19.000.000 ($1900). And canon so much better in service after sales. I pick canon over nikon anytime anyprice.
