According to Famitsu, the DS Lite passed the 10 million units sold mark in Japan during the past month. The handheld sold 702,843...wait *recounts* sorry, 702,844 units in April, nearly two and a half times it's closest rival, the Nintendo Wii. I suppose that isn't really a rivalry. That's a pizza party at the Nintendo offices, that's what that is.

Worldwide the DS Lite has sold 22 million so far, with the DS line in general over 40 million.

So half of the DS Lite sales in the world are in Japan. I think we can attribute this to Japan's population density of over 870 people per square mile. The DS has proven an excellent way for Japanese people to look at something other than other Japanese people for five minutes. In contrast, the US population density is only 80 or so per square mile, which is good because sometimes we smell weird. Not bad, just...kind of off, ya know? Michael Fahey
