It is simply that there hasn't been a cross market blockbusters like Pokemon, Brain Age or Nintendogs that can push the 3DS to DS sales territory.
But beyond that, it pretty much comes down to the fact that the West (or more specifically the United States) aren't into handhelds as much as Japan. Heck, in Japan, the portable devices are pretty much King since early in the first console generation. But after little less then a year, I don't think it is valid to say it isn't doing well in one territory when the difference is about a million and as I stated, the DS at around this time had its major genre busting games being first released.
