Speaking during an investor briefing on Tuesday, Nintendo’s president Satoru Iwata said that sales of his firms new 3DS portable gaming system failed to meet expectations. “Sales of the 3DS have been weaker than expected since the second week of launch in the US and Europe,” Iwata said while discussing the device’s launches in Europe, the United States, and in Japan. Nintendo had expected to sell 4 million units last quarter, but sales fell short at 3.61 million units. Iwata said that he hopes sales will increase as much as 40% during the next year, AFP reported. We reviewed the 3DS earlier this month and argue that the gaming system doesn’t offer enough features to justify its $250 price point.
