He didn´t say what revised ranger. As of now there are lots of versions, because there is no official alternate ranger version.
Officially the RR ranger of the WOTC´s UA in 2016 was shut down (And was never official to begin with, it´s just playtest material). I hope you are right and the Larian guys revive the old one or make a custom version for the game.
