That, as I have bored many of you with, would be my dream camera, 24-28MP with a better sensor in a 1 series body.
Fingers crossed on this rumour, it would also be another interesting differentiator between the high MP Nikon bodies.
As for colour, in a studio environment particularly, there is no excuse for inaccurate colours already, though it is surprising the number of people, high end pros included, that just don't understand camera profiles, profiling, and a decent colour managed workflow, what are their assistants doing?
P.S. There have been so many 1DX deals around recently there might be a little more to this rumour than most, I'd love to know the fps, if it is aimed as a 1DX MkII it can't be slower than currently. If the 1DX truthfully was an amalgamation of the 1D and 1DS lines then it is high time for a camera with better "studio" specs than the 1Ds MkIII, if that got a high frame rate too it would be THE generalists tool. No more lenses for me this year
