i own the 1dc since january and did shot with it all over the planet from carnival in venice to havana (sometimes alongside with a red epic which makes them a great allround team for all situations).
in all terms it is simply the best available DSLR so far, with brilliant video resolution, unbeatable lowlight performance, and only topped in photo resolution by the d800.
i love it and would definitely not exchange it against a 5D3, GH3 or BMC!
the form factor is perfect for shooting fast and shooting with fun (and also shooting photos), way better than the odd bmc/c100/c300/c500/alexa form factors that are no joy without rigs.
most cons listed here are (at least for me) irrelevant or can be worked around.
I even don't find it expensive, as right now I don't know any camera that delivers such beautiful 4k images (and can use all canon/nikon/zeiss full frame glass) for less than app 8200 euros+tax.
of course I would be happy if canon comes up with even more features and improvements for even less money, so that I would not have to buy any new camera the next 15 years, but that's not realistic.
I think if canon bashing is taken too far, the risk is you are not heard at all.
