I suspect 6D will be a super success.
I will not buy it but I know of lot of people around me who want an inexpensive full frame camera with good IQ.
They are casual photographers who want super quality for a super price without the 'bells and whistles'.
The world has far more 'casual' photographers who want value for money compared to photographers who want everything on their camera.
Well, it remains to be seen if the 6D will be perceived as good value for money.
Basic, consumer-level specs ... for $2099 ... is not good value for money in my book.
The thing is, even if the 6D drops to $1500, I'll still have my doubts.
The basic AF system on the 6D is certainly not confidence inspiring.
And what good is a gorgeous FF sensor on a camera that can't focus.
That's my view of things.
