I found Cherry's Korean site by accident today (
http://cherryko.co.kr/), and discovered they have two KO-layout keyboards listed. They're both branded MX-Board. I speak no Korean at all, so if anyone can add more detail to what I've gleaned please feel free to do so!

(Warning: for some reason Cherry have combined their product photos into one ridiculously tall image - so I've picked 3 for each keyboard, and linked the full "set".)
G80-3497. A 3000 variant, branded MX-Board - so a Korean equivalent of the 3494 and 3600. Blues, Browns or Reds (codes LSCKO, LXCKO, LYCKO respectively). NKRO; USB / PS/2 combination controller. Light grey or black colour schemes (not that you'd know there was a light grey from the photos

). Seems to have some sort of custom profile system (so does the 1867) - needs a translation for more detail.

G80-1867. An 1800 variant, with the MX-Board brand again (are any other 1800s branded MX-Board?). NKRO and combi controller. Only comes with Blues and a white case (code LSCKO-0).
