During an interview at the Gstar international game expo in Seoul, Microsoft Korea spoke with Gamasutra about relative next-gen marketshare in the local sphere.
When pressed about the Xbox 360's total units sold in South Korea, Dae Hwan Lim, marketing coordinator for Microsoft Korea's entertainment & device division (which includes the Xbox 360), conceded that "I can't say myself, but some reports here said about 100,000."
Squeezed for further details, the marketer remarked that the "Xbox 360 is doing much, much better (than the PS3). There's a huge gap in market sales. I can't mention other company's numbers directly, but it's multiples larger."
