A thought I just had: There seems to be a lot of concern on this post as to who will buy this camera. That this camera won't sell well. And my response to this is.... Who cares? I would be totally fine if this camera only sells 1 unit worldwide (and that would be to me of course...). We should really be less concerned with Canon's sales numbers and more concerned with our own creative output.
'Who cares?' - Canon cares. And their owners, their employees, their distributors, their suppliers etc etc. If this model is a total disaster it impacts everyone who holds a Canon or intends to do so. Lower profitability, less money for R&D, fewer new and useful products.
But you don't care....
I care. I want this product to fail, and fail badly. It's 4 years too late, it's almost practically the same as the 5D mk2.
4 years ago it was innovative. 2012, it's boring, it's overpriced.
Canon used to be innovative, now they're just a fat loser (wearing an "I'm number 1 so why try harder" t-shirt) getting rich on successes of past years.
I'm not switching to another brand, I can't, too many lenses and not enough cash.
So that means I, the loyal Canon user, who was suckered in during their 'glory days' of 5D2, 7D, 1D4, can do nothing to 'upgrade', because there is no 'upgrade'. 5D3 is an 'upgrade', yes, but i don't have that kind of money. 6D is no more of an 'upgrade' that a 5D2, used or new, and the 5D2 is cheaper.
I hope D600 sells big. I hope the a99 sells big. I hope the K3 isn't just a pipe-dream and sells (as) big (as pentax can make it).
I hope the 6D bombs and bombs bad, so that canon are forced to re-think "now why did this suck balls so much?", and they come out with something that is truly revolutionary (like the 1Ds was, like the 5D2 was), not a backpedal (like 1D4 -> 1DX was for birds/wildlife), and not treading water like this 6D is (4 years later and what, it's got a gps and wifi chip? what else? uh, nothing? same pricetag, MP, AF, and worse sealing? No Thankyou.).
