"Specifications" leak for the 1DX Mark III

I'm not convinced these are the real specifications for the 1DX Mark III - dual DIGIC 6+'s is not right and CFast is mentioned for memory cards.  That's just not happening with the 1DX Mark III.

Canon has done similar things in the past where they update the specifications from the older camera model, which is what it seems they are doing here.  If you recall, the 90D leaked specifications were a similar hot mess.

So, as far as we're concerned, while this is showing that Canon is getting closer to releasing the 1DX Mark III, do not take these specifications as the final result.  The section after the main specifications seems more legitimate which makes me believe we're seeing sample documents being updated.

Since they are circling the web, we feel the need to publish the specifications and also weigh in on them.

So here are the quasi specifications for curiosity sake:

Need for Speed
The Canon EOS-1D X Mark III will be blisteringly fast – offering exceptional precision, reliability, high-performance autofocus, and subject tracking – providing photographers with a tool that will help to capture the shot they are chasing. The camera’s new autofocus algorithm will improve stability and tracking when using both the Optical Viewfinder and in Live View shooting mode, using Deep Learning Technology and adapting to help facilitate accurate focus tracking for every shot. When using the optical viewfinder the camera will use a new autofocus sensor, with approximately 28 times the resolution in the center of the EOS-1D X Mark II. Offering the ability to autofocus in even brighter and darker situations than before and with greater precision, the camera will have a range of autofocus capabilities, which will enable the photographer to get their shot. In Live View mode, users will be able to make use of 525 AF areas using the Dual Pixel CMOS AF system will cover approximately 90×100 percent of the image sensor. The camera will support significantly faster frame rates with full AF and AE, using either the optical viewfinder (up to approximately 16 fps mechanical shutter) or Live View (up to approximately 20 fps mechanical or electronic shutter). Additionally, the camera’s dual CFexpress card slots will enable more than five times the RAW burst depth of its predecessor.

Powered to Dominate
The development of EOS-1D X Mark III is a clear example of Canon’s commitment to pushing the boundaries of innovative imaging products featuring optically excellent technology. The camera will support an all-new, Canon-developed, CMOS sensor and DIGIC processor, that will deliver greater image quality, at even higher ISOs, with the ability to capture stills in 10-bit using the HEIF (High-Efficiency Image File) file format. HEIF produces wider dynamic range and greater color representation compared to JPEG. The power of 4K resolution brings stories to life – shoot 4K videos including 4K60p with 10-bit 4:2:2 Canon Log internal recording.

Conveniently Connected
For professionals, content delivery is just as important as image capture – the EOS-1D X Mark III will make it easy, featuring built-in Wi-Fi and Bluetooth low-energy connectivity in addition to GPS technology. To keep pace with ever-shortening deadlines, the camera will transfer data at more than twice the speed of the EOS-1D X Mark II when using the built-in Ethernet connection, or the new optional wireless file transmitter – the WFT-E9, which is also compatible with Canon’s recently launched Cinema EOS C500 Mark II camera. Coupled with simpler network set-up the camera will greatly enhance the professional workflow

A Familiar Feel with Improved Attributes
Existing EOS-1D series users will be familiar and comfortable handling the EOS-1D X Mark III allowing seamless navigation with trusted ergonomics – whilst the magnesium alloy body will offer the durability expected from Canon’s EOS-1D cameras. Professional photographers can trust the same impressive build-quality as the EOS-1D X Mark II – with phenomenal weather-sealing, standing up to harsh conditions, including wind, rain, and humidity. With incredible low-light shooting capabilities, the camera will now feature select illuminated buttons that allow for precision operation in challenging, dark and dimly lit conditions. The camera will also offer a new additional control for selecting AF points, built into the AF-ON button, allowing photographers to change AF points on-the-fly for the best composition – further helping to simplify their work. In addition, dramatically improved battery life – with the same LP-E19 – will allow professionals to shoot for longer periods of time, without having to change batteries, helping reduce the chance of missing a shot.

A new era in autofocus speed and accuracy
The EOS-1D X Mark III will feature a brand-new AF sensor with 28x more resolution than its predecessor, using advanced AF algorithms with deep learning technology for incredible focus tracking in any situation. And in Live View and video, there will be the added advantage of Dual Pixel CMOS AF across approximately 90×100 percent of the sensor with 525 AF areas. With AF over a wider EV range focusing with an EOS DSLR truly will never have been more accurate and versatile.

Outstanding stills and video
With a new Canon CMOS sensor and powerful new DIGIC processing, image quality even at high ISO will be taken to even greater levels along with 4K video at 60p, plus the options of capturing RAW video or 10-bit 4:2:2 video with Canon Log, both recorded internally to CFexpress cards. A new bright viewfinder will help connect you to your subject in real time.

High-speed camera communications
Delivering captured content quickly is the vital next step for a professional. This is why the EOS-1D X Mark III will feature Wi-Fi and Bluetooth low energy connectivity and GPS capability for seamless communication. With double the transfer speeds of the EOS-1D X Mark II, via the built-in Ethernet port or through the optional WFT-E9, and with a revised user interface for simpler and more intuitive operation, the new EOS-1D X Mark III will be designed to get the job done faster than any EOS ever before.

Always ready to perform, whatever the situation
The EOS-1D X Mark III will be radically upgraded for superb performance. Not only will it offer a blistering frame rate with the optical viewfinder including AE and focus tracking, but also dramatic improvements in Live View mode with the same level of accuracy, plus the ability to shoot using an electronic shutter. The camera will be engineered to excel in all areas, with dramatically improved battery life using the LP-E19 battery, new illuminating buttons and an all-new AF point selection control within the AF-ON button in addition to the multi-controller. All in a magnesium alloy weather-sealed body.
