This rumor seems farfetched, though. If Canon could create a self contained camera that could continuously record RAW and compressed images at 30fps on a global shutter, it would have a huge impact on both the video and photography markets. Nothing comes close right now. The 1DC is a pale imitation since it can only record non-continuous 12fps RAW and 24fps compressed at APS-H crop on a non-global shutter.
The Dragon records 6K at 100fps, or extrapolated to 8k and a 3:2 aspect ratio still 40fps at full resolution. Or the rumored 52MP at 30fps. Global shutter included,the target audience isn't to fond of yello (behind the lens at least).
Or in the more consumer orientated segment you get 6700MP/s capacity, enough to go through 8K at >120fps, in a package smaller then the 1-series.
For raw storage you'd need a breakout to an SSD-raid though.
