At this price point I suspect the camera goes from "nice tool of an artist" to "business expense ofa team". With that I think people with this budget prioritize modularity and reliability over the convenience of having a all-in-one device.

Like for the Olympics there's mention of using a gizmo (PDT-FP1) whose sole role is to connect to the camera and transmit the picture wirelessly (even though the A9 have some wifi connectivity). And of course this wireless transmitter is quite expensive.

In cinema they have the same approach, as you don't buy "a camera", but you rent a sensor, a lens, a monitor, a focus pull, a storage disk, etc.
