Pokemon Platinum on DS, which came out in North America in March, right before the quarter started, moved 1.91 million copies in Q1, for a life-to-date total of 5.66 million worldwide.
It was an even better quarter for the Wii's evergreens. Wii Fit sold an additional 3.6 million copies, bringing its LTD to 21.82. Mario Kart Wii sold 2 million, making its total 17.39 million. And Wii Sports sold an additional 1.91 million copies, bringing its total sales number to a ridiculous 47.62 million, including copies sold in hardware bundles.
And that's why there's a sequel.
