To combat making only slightly less obscene amounts of money this fiscal year (April 2010 – March 2011), Nintendo will release its 3DS handheld, Pokémon Black and White, Metroid: Other M and Super Mario Galaxy 2. The company's new strategy: "to achieve the ultimate worldwide objective of 'must-have for everyone' rather than 'must-have for every family.'" Conveniently, this strategy suggests that the Wii Vitality Sensor, which is also scheduled for release in the coming months, need only be supported by a single, heartfelt purchase to be successful. (Oh, who are we kidding -- how many units has Wii Fit sold?)
Summing up Nintendo's fiscal year ending March 31, 2010, the DS sold 27.1 million units, bringing its global sales total to 128.9 million units. (The company has high hopes for continued sales of DS models, including the 3DS, as it forecasts general platform sales of around 30 million units this fiscal year.) Additionally, the Wii moved 20.53 million units, bringing its lifetime sales total to 70.93 million units through the last fiscal year. (Nintendo expects to sell around 18 million Wii units this fiscal year.) Finally, software sales were highlighted by New Super Mario Bros. Wii, which sold 14.7 million units worldwide last fiscal year, following its launch in November.
