wow ... http://home.comcast.net/~NikonD70/Charts/PDR.htm#EOS%205D%20Mark%20III,D600,D800
D600 sensor has same DR as D800 ... 6D will suck air.
Lol, do you think that matters with Canon or the customers? Sensor is the last thing that matters to regular public. They will more likely attracted by the bundled package including free UV filter, lens cleaning brush, and of course Canon's award winning customer service.
They won't care about the free UV filter, etc, it will be "ooh, that camera has 24megapixels and this one only has 20, I want the one with more!"
Suuure nobody reads the reviews.. The customers (at this price range) spend their 3k on a camera just because it has more megapixels than the rival model... Yea sure..
They guy who spends that amount of money for a camera is probably not part of the "regular public" (whatever that means).
