I’d be surprised to see native CinemaDNG ever either as it’s barely implemented in Adobe’s own NLE. Problem is it’s basically terrible for playing back at full speed in decent performance because it’s a massive sequence of images vs. a continuous video stream. Better workflow is proxy it for FCPX and then grade to DNG in Resolve.
