Is this the exact same design, form-wise, as the 1DX? If so, it's probably almost the same camera but with upgraded firmware and a considerably higher price... APS-H is also an annoying crop factor for video. Super35 is much closer to APS-C and there are fast wide zooms for crop bodies.
I want the APS-C cinema camera!
To those fawning after the Red...sure, it looks nice, but the poor color rendering, impossible proprietary workflow, and constantly-in-need-of-updates software make the camera a nightmare, imo, to use. Canon's footage has nicer skin tones than I've ever seen out of a Red. There's a reason so much tv is shot with the Alexa, rather than the red, and why dSLRs are used on ads--1080p with nice and standardized colors out of camera is much better for post. Red is cool, but what you get in terms of extra tech you pay for in having to figure out how to use it efficiently. Canon's cine camera does seem overpriced for what you get, though--in that no man's land the AF100 and F3 already inhabit except even more expensive...
