Or you could already know or learn Korean, obviously, but that might be a bit much for a fairly simple preview of the game’s next areas.
These new areas do not have a release date yet for the US version of the game, although it’s still early in the year. Players will be able to explore new lands and presumably continue the game’s main storyline, so players are no doubt excited to see what’s in Drieghan. And you can see it right now… a small slice of it, anyhow.
