Nice find!
BT-DN300 - I'll take that as the definitive confirmation that any wires will be EW-SD300 type

Hydraulic components on this bike are old (ST-R9180 + unknown caliper), next gen hydraulic hose fitting may be different.
But more importantly, compatiblity with old tri hydraulic shifter ST-R9180 confirms compatiblity with rim brake shifters
ST-R9180 can be wired and can be powered by new battery BT-DN300, so
ST-6770, ST-6870, ST-R8050, ST-R9070, ST-R9150 can also be used like that
(full set of di2 adapters included in the listing)

I don't think the hose and connections change, apparently there are improvements in the calipers, but I suppose it will not affect the connectionsooo wrote: ↑Sun Apr 18, 2021 10:10 pmHydraulic components on this bike are old (ST-R9180 + unknown caliper), next gen hydraulic hose fitting may be different.

Cassettes will features new interface, which is compatible with new freehub (new d-a disc/rim wheels) and old freehubs (new Ult disc wheels).
No separates hubs with D-A or Ult branding.
Rim brake calipers looks similar to 8000/9100, disc calipers are different (easier to bleed like br-m6100/m6000), hydraulic hose and connectors are the same as 8000/9100.
12s cranks chain line is +1 mm over 11s cranks
