I've been unable to find anything by Googling, but just in case, has anyone heard anything about Korean adoption of either HD disc format? In the past, Korean DVDs have usually always included English subtitles, so this'd be a great boost for hi def if it happens.
I believe Blu Ray has been released in Korea (don't think HD-DVD has). http://www.dvdfromkorea.com/ has a few BD titles listed, but I don't believe that its doing great as a format over there. Not sure how prominent they will be with releases.
