As someone who has done extensive power usage tests with the 12th gen, I can say I am delighted to hear those news, and I have high hopes it will improve the rather problematic situation of the expansion card power usage (especially on standby).
I do have to ask, however: the update will be available on Linux (yay!) but will it be distributed with the (de-facto) standard LVFS mechanism? It’s still unclear what Framework’s position is on this (cf. Framework firmware on the LVFS?) right now…
