I'd say it's basically impossible. How many DS units have been sold in North America? Over 20 million? To accurately sample that population you'd need to survey over 3000 people and ensure that it was representative of the group (kids, seniors, etc). Unless his group is representative, it's entirely meaningless. That being said, I think it's going to be impossible for them to even know WHAT representative means for the DS. It would require detailed survey work on what types of people buy the system, which only Nintendo would have. Besides, such surveys to determine that would miss the whole Brain Training group.
