Along the same line of thought, why would a C70 Mk2 have a worse Wi-Fi module than R1?
Here's my thinking: As Wi-Fi 5 has lower bandwidth and higher latency than Wi-Fi 6, the use case of the ID0179 camera is likely to require less bandwidth and be less sensitive to latency than the DSxxxxx camera.
It wouldn't make sense to put two different modules into two almost identical products, like the proposed R1 and R1C.
I think it's much more likely that the two cameras are highly different.
So if the ID0179 camera is a video camera (PTZ or Cinema line), it is likely to be for remote control, rather than live streaming of high-quality high-resolution video.
Sure, 4K H.265 video stream could be supported by Wi-Fi 5, but that's a compressed stream.
The DS camera could support Wi-Fi 6 to have fast wireless transfer of (still) images, something that could be compatible with the idea of a Pro level camera (think R1).
I've certainly never used the wireless data transfer of my cameras, so I don't know what would be important for the type of photographers that need/use this.
As others have said, it's likely that everything will be revealed at CP+.
