No, not a typo. Not a joke. Japan MapleStory will be the first service of MapleStory outside of Korea to receive the Legend update.
Cannon Shooters and Mercedes arrive on October 19, Demon Slayers on November 16.
Check out the teaser page at http://maplestory.nexon.co.jp/campaign/legend.asp.
The next “Fastest Updating” and “Most Updated” rankings aren’t due out until the end of the year but I have a feeling we’ll see JapanMS rise on both lists unless the other services of the game make some surprising announcements soon.
