So, uhm, basically, you've got no clue how things in Japan work. I can't even begin to tell you the amount of photos people take with their cellphones over there, and a lot of those are sub-5MP cameras. Putting a camera in the DS wouldn't be for anybody looking to replace their real camera, it would be for people to have fun with, take pictures with friends, have fun adding and editing photos with the touch screen, sending back and forth to friends, etc. No way in the world the camera in a DS would need to be anything more than a 2MP camera, and I bet it'd be a HUGE feature.
