Some quick takeaways from the Icom IC-905 Introduction video a few minutes ago:
The narration was in English (in the version I watched), so easy to follow!
The control unit does not have any RF circuitry; all the RF circuitry is in the external unit.
Power output for 144 / 430 / 1200 is 10W (Type N connector).
Power output for 2.4 / 5.6 GHz is 2W (separate SMA connectors).
Power output for 10 GHz is 0.5W (connector unspecified).
10 GHz capability is optional, via the CX-10G transverter (a second external unit).
Amateur Television (ATV) is a built-in mode, but requires an analog camera. ???
Control unit includes a (full size) SD card slot and USB-C connection.
Icom mentions mobile operation as a use case.
DD mode (128 kbps) is fastest data rate
There was no indication that the connection between the two units can be virtualized via Internet. All the illustrations showed the control unit connected directly to the external unit.
I’ll be watching the discussions this week and have a more complete set of impressions in Zero Retries 0061 next week.

There once was a product that used VHS tape to back up hard drives. Perhaps there may be a way to come up with a way to send/receive data using the ATV mode.
Since the ‘control’ unit seems to be based on the IC-705, maybe the wireless network and/or Bluetooth functionality will be retained in the IC-905…one can hope…
Looking closely at the body in the video (which is still available) shows both LAN and RF Unit RJ-45 connectors! Sent Steve a screen cap via SMS since I can’t seem to include it here.
It might not been good for V/U band to use the remote head amp. By doing that, you'll need to find space to mount the head amp if you are just UV fans. BTW, any mention on the full/half duplex ops mode, can V/U operate simultaneously in the way IC-9100 does ?
The unit has analog AV input/output jacks, it makes sense to use an analog video input in my opinion... now, to source an analog camera...
Power for the RF unit is carried over POE, which likely limits RF output levels.
The ability to actually carry control signals over IP/internet would depend on ability to recreate POE at RF site.
I suspect remote operation will be thru RS-BA1 software.
Only one N-Type for the 144/432/23cm output - need a splitter and yet another loss of power at the masthead, and no specific output to control a linear or preamp at the masthead either?
