The 6D was never intended to better the 5D3. It's fills a niche between the 5D3 and 7D in the EOS portfolio. Those who are trashing it for not meeting or exceeding the 5D3's specs don't seem to understand that.
I haven't heard of many normal people(with maybe one aging aps-c body and one or two lenses) choosing the 6D, only pro's and serious enthusiasts who just want a new Canon toy.Depends what you mean by "normal", I guess, but I went from a Rebel XT to the 6D. Oh, and- yeah, not counting the Rebel's kit lens, I only had a 40mm pancake and EF75-300...
I fully understand that. But for Canon to leave out the 7D AF or better in a time(2012 not 2009) when nearly every Nikon has a better AF was pretty weak. All the new Nikon updates have at least a 39pt AF while Canon is still offering the same 9pt AF system that was lame when the 5D II came out years ago. For me, it wasn't impressive at all, especially for the launch price.
I'm sure lots of people disagree with me and are happy with the center point AF, but for me, I was over it. I already had a Canon 5D and the only problem was the ISO and the AF.
I waited for the 6D for a while as I have been wanting a lighter FF body for years(I travel a lot,) but when the specs were announced it was way too easy for me to not be interested in the camera, especially for $2100 dollars.
