The 1D4 was one of Canon's premier bodies. Too bad they nixed the APS-H format. However the 5D4 (and the EOS-R having a similar 30Mpx) sensor can be cropped to the 1.3 crop factor, and have more resolution than the 1D4, and will have better DR and high ISO performance to boot. So today's FF bodies already cover a vast majority of the 1D4 resolution and capabilities. So if you get a 5D4 or the EOS-R, I doubt you will miss the 1D4 that much after using it for a couple of weeks.
Agreed, the ONLY things that the 5D4 looses to the 1D4 are FPS, Tanklike build quality, and that perfect built in portrait grip. For me, I prefer the 5D4's lighter weight, so I happily give up the last advantage. I've yet to require a camera body that can be driven over by a Cadillac, and I really don't miss the FPS, so for some the 5D4 actually looses nothing,..
...and of course it gains SO MUCH
