I'd been thinking the impending 12 speed dura ace would be semi wireless with the mechs connected to a battery but maybe not.
The patents show removable batteries on the mech just like Sram AXS.
The patent drawings seem to show mtb stuff with the dropper post. It seems they have teamed up with Fox suspension for the integrated control stuff on the forks and post.
