Anyone else think that maybe the propeller-heads at Canon designed the 6D down to the *rumoured* price of the D600 ($1599) instead of the actual price ($2100)? I can just 'see' the party in the weekly Product Development meeting when Nikon released their price... and if "They" are selling at over 2k, why not do the same? After all, it's too late to add an autofocus system back into it, this close to market.
All I wanted was a FF DSLR with a decent AF system and reasonable IQ in variable light for dog sports. I don't even care about >4fps. The rest of the time, I could even do MF! Don't care about video. I'm not 'committed' to anyone's system yet, as I've been waiting to see what was coming out this year. Nikon might have an edge on the bodies right now, but for the focal lengths I'm looking at, Canon has the better glass.
Yes, I could probably get away with a 7D for the sporting stuff, and a 6D for everything else... but that would mean lugging two compromise bodies around for the same price as a 5D3. Put the 7D AF system in the 6D and I'd probably perorder it. Hell, you could even take the "OK, but not perfect" sensors from the 1DX production line and stick them in a lower-end FF camera for all I care. 18MP is plenty. I'd rather have another stop or two of clean ISO than 4-6MP.
It looks like noone wants my money unless I give them ALL of it. Looks like my 30d might have a couple of years left on it... perhaps with a 70-300. Maybe even a 70-300 L. Case in point of elasticity of demand. Stretch the customer too far, and they walk away. You get 100% of nothing. If the prices here in Oz were on parity with the US or HK, it'd be harder to walk away... but with 20-30% margin? These shoes are walkin'.
(And yes, I'm aware that Canon have decided [or justified, retrospectively?] that the target market for the 6D is travellers/tourists, who don't need more than one AF point.)
