Canon recently announced the 1dX, the successor of the 1dMK4.

Here is what we know so far of the camera that is relevant for the video features:


Video. The Canon 1D X offers Full HD (1,920 x 1,080 pixels) video capture capability, as well as a couple of lower-resolution options, and a healthy selection of frame rates. At the maximum Full HD resolution, recording rate options are 29.97, 25, or 23.976 frames per second. At 720p (1,280 x 720 pixels), there's a choice of either 59.94 or 50 fps recording. Finally, there's a standard-def mode which offers frame rates suited for either NTSC or PAL display. In all cases, the EOS-1D X uses H.264 compression.
As you'd expect given its flagship, professional camera status, the Canon EOS-1D X provides a lot of control over how videos are captured. Both automatic and manual audio level controls are available, with the manual mode offering a fine-grained 64-step control. It's possible to adjust the levels during capture, and sound recording can also be disabled altogether. There's an optional wind filter function, and sound can be recorded either with an internal, monaural microphone, or an external stereo mic.
The videographer can also control the H.264 compression system used by the camera for HD video, opting either for ALL-i intraframe compression, or IPB interframe compression. The latter considers multiple frames when compressing the video, allowing higher compression levels and more efficient file sizes, but also increasing the burden of post-processing. Intraframe, meanwhile, is similar to Motion JPEG capture in that compression is restricted within each frame, making for higher file sizes but easier editing.
There are also two methods of embedding timecode in the 1D X, with one tracking timecode only during capture of video, and the other including timecode across an entire capture session, including periods where the camera wasn't recording.
Another new feature is the ability to automatically span videos that exceed the maximum 4GB clip length across multiple files. Canon notes that no frames are lost in this process, and so the files can be joined back together seamlessly in post processing. The maximum capture length is still limited to 29 minutes and 59 seconds, however.

Sensor. Canon has developed a brand-new, high-performance full frame CMOS image sensor specifically for the EOS-1D X. With a pixel size of 6.95 microns--some 1.25 microns larger than those of the 1D Mark IV, and 0.55 microns larger than those of the 5D Mark II--the 1D X's sensor is said by the company to have the lowest noise of any EOS digital camera to date. Further enhancing light gathering efficiency, the 1D X's CMOS chip includes gapless microlenses. Resolution is 18 megapixels, almost exactly splitting the difference between the 16 megapixel 1D Mark IV, and the 21 megapixel 1Ds Mark III. To ensure all that data can be read off the sensor quickly enough, the design includes 16 readout channels. Analog to digital conversion is 14-bit.

Sensitivity. Between the new image sensor and image processors, Canon has been able to extract a very wide sensitivity range from the EOS-1D X. The base sensitivity is ISO 100 equivalent, and ordinarily the 1D X tops out at ISO 51,200 equivalent. This range can be extended at both ends, reaching a minimum of ISO 50 equivalent at the bottom end, and a whopping maximum of ISO 204,800 equivalent in the H2 setting. Overall, sensitivity is said to have been improved by around two stops over the previous generation of cameras.

and of course:

Pricing and availability. The Canon EOS-1D X is scheduled to ship in the US market from March 2012. Body-only estimated retail pricing is expected to be in the region of US$6,800.00. The WFT-E6A Wireless File Transmitter will ship at the same time, priced at around US$600. Finally, the GP-E1 GPS receiver will follow from April 2012, with an estimated price of around US$300.

What I would like to know is, do we get clean HDMI output in 422 / 10bit without any focus blocks or downsampling?

nope, still the focus block on video out ... but the codec it uses is pretty impressive, so that's not a dealbreaker.
