On September 12, Nintendo will drop the prices of their two DSi handhelds by $20. The DSi will be $149.99 and DSi XL will be $169.99. The DS Lite model will remain at $129.99. Says Nintendo’s Cammie Dunaway: “We know shoppers want to get the maximum value out of every dollar they spend. Our new Nintendo DSi prices make it easier than ever for consumers to access the tremendous variety of games, applications and social tools on the Nintendo DSi and Nintendo DSi XL systems.” The press release announcing the price drop also shared this tremendous stat: According to the NDP Group, “through the end of July, total Nintendo DS family hardware sales are more than 42.3 million in the United States alone.” Wowzers. With the DSi lineup at a lower entry price and the 3DS readying for a launch (a release date is expected to be named soon), there really is no stopping the killer incentive to purchase a Nintendo handheld.
