Got this info from Reddit. Apparently Nintendo sold over 55K in South Korea. This number beats not just the launch week sales of the DS, Wii and 3DS, but also the launch months sales of those devices.
Here's the article (in Korean): http://bbs.ruliweb.com/nin/board/300004/read/2148024?
It seems that Nintendo has put some effort in these markets, wonder how it will perform in China and Taiwan.
