Then the same kids who bought a DS will likely end up buying a Wii in the future.
The DS wasn't even available in Korea (or anywhere for that matter) when I was living there, so I never saw any kids playing with Nintendo handhelds.
The Advance SP was available, but game selection in the electronics mart was very limited. The only carts I bought were compilation carts (non-licensed carts with dozens of games on them). In in the two years I was there, I cannot recall seeing a single Advance not owned by an American.
