in the crowdfunding campaign, the "AXIOM Beta 4K RAW PC recording option" got funded as a streched goal.
There are several concepts but there is no definitive technical solution for that yet.
- use the 3 HDMI Ports from the Axiom and connect it to a 3 Port HDMI Interface Card, combine frames in software to get 4K in high framerate
Bertl: SDI is an option as well, but requires additional soft- and hardware on the camera side
Bertl: gigabit ethernet is way to slow for transferring 4k raw in realtime
