This specification is only about the data bus, not the power bus, since they're separate in USB-C. So no, this will not bring higher power (and higher power won't need to wait for a future USB-5 standard).

thank you for the explanation! Do you happen to know if there's any work on bumping the power bus to 130W?

I see that USB PD rev 3.0 allows up to 100W - https://en.wikipedia.org/wiki/USB#Power-related_specificatio...

Is there any work on rev 4?
