Kotaku reports:

Sales in the “Americas” for the DS Lite from the day it hit here on June 11, 2006 to the end of September were 2.23 million units. While Sales in the “Americas” for the DSi from the day it hit on April 5, 2009 to the end of June were 1.56 million units.

That means the DS Lite sold on average about 20,000 units a day at $130 a pop during the 112 days of that reporting period, while the DSi sold on average about 18,000 units a day at $170 a pop during the 87 days of it’s reporting period.

Could it be the higher price with the weaker economy leading to these slower sales figures?

Our hunch is it s a combination of that plus the fact the Nintendo DSi isn’t significantly better than its DS Lite predecessor to make players plunk down another $170.

Plus, has anyone seen a killer app for the DSi yet? Not saying that it isn’t coming, but as always, software rules the world, even when you have Beyonce in your corner.
