official compatibility:

old battery (DN-DN110, etc) is NOT compatible with 12s shifters (you cannot update to new STI otherwise 2x11 di2 bike)
old battery (DN-DN110, etc) is NOT compatible with 12s derailleurs (you cannot update 11s to 12s by changing just RD/FD)

new battery (BT-DN300) is compatible with old SINGLE-BUTTON di2 shifters (TT), it is NOT compatible with old DUAL-BUTTON di2 shifters (TT/road/grx/mtb)
new battery (BT-DN300) is NOT compatible with old 10-11s derailleurs (only 2x12 is possible, it is impossible to shift 2x10 or 2x11)

12s hydraulic shifter can be used in semiwireless and fully wired setup,
12s rim brake shifters can only be used in fully wired setup

not released so far:
no mechanical shifting
no tt specific di2 shifters
no new pedals
no new rotor, chain, bottom bracket, hubs

expected release at later time:
11-28T cassette

I think the bigger takeaway is the the "old/current" 9100 and 8000 generation brifters are compatible with the new calipers.

The hydraulic components of 9170 shifters look to be compatible with 9270 calipers as per that chart but I thought that there were issues with 9150/9170 shifters being compatible with 9250 derailleurs?

Yes. But isn't that the most important part? If you are running a R9100 groupset, the brake upgrade looks very attractive for the extra clearance and reduced weight

I suppose it is if you're not looking to go to 12 sp.

Not sure where the surprise comes from? It was well known already for a while that 12 speed shifting stuff is not going to be backwards compatible with 11 speed. Of course, not because it couldn't be made compatible, but because Shimano decided it to be so.
So the fact that we get at least official brake compatibility, is a nice bonus :thumbup:
