Korea is always late on stuff like this, and Taiwan is even later. First party games in Asia usually go Japanese only, then get translated to Korean, and then finally Traditional Chinese. That's why in Taiwan they import the Japanese and American version of games, because Nintendo doesn't release a localised version until a year or two later if they're quick.
Miyamoto visited Taiwan to promote the 25th anniversery Super Mario Collection, and also said Nintendo was in the works of translating Super Mario Galaxy 2 to Chinese (Traditional). They'll probably get that in 2011.
