Why do we do this every year? The summer months are the slow period for the industry. Sales for 360 and PS3 were dropping really low as well - the PS3 was nearly at 30k/week in the US. The price drop fueled sales in this downtime. Nintendo didnt have a price drop, so they didn't get a boost.
If you want an accurate picture of what Americans want, check the Nov and Dec sales. Holiday purchases for outpace sales for the other 10 months combined.
