It looks like the western version won’t be gating a lot of regions since besides Rohendel, we’ll be getting the Yorn, Feiton, and Punika regions. Level 60, T3 gear and content will also be part of the launch content.
Surprisingly, a much requested option (which I was also requesting) has made the cut: the original Korean voice over. This will be available as an optional free DLC (subtitles will be available for the supported languages; the Korean subtitles however won’t be available – which isn’t a problem given this is the western version).
Additional details regarding character and guild name restrictions are noted in the update posting.
