Now that we know that the 5D Mark III will be getting clean uncompressed HDMI by April 2013, I think it's time Canon also confirms this feature also will be made available for us who chose to spend even more money on buying the 1D X.
I work with both stills and video, and I bought the 1DX for it's extra low light performance and DR over the 5D3.
Given what we now know, that the much cheaper 5D3 will get clean HDMI out, it will be absolutely unacceptable if the 1DX does not get the same upgrade!! We know it is possible since the 1DC already have this option on 1080p footage.
So I really hope Canon would please give us who spend all our money on them, what we want!!
It would be remarkable if the 1DC and the 5D3 should have clean HDMI out, and the 1DX would not!!
This would mean Canon would try to force me to sell my house to get the ISO and DR performance on video of the 1DX through the 1DC. Which of course will not happen!
A faster and cheaper solution may be to just buy the Nikon D4!
