Mario Kart Wii and Wii Fit were part of the reason for this software success, since in the quarter Wii Fit sold 3.42 million copies and Mario Kart sold a whopping 6.42 million units. And, if you weren't yet convinced that Nintendo deserves the "printing money" meme, the company is projected to bring in a net profit of about $3 billion dollars for the year.
We don't know about you, but our own wallets and bank accounts are growling with envy.
Update: Fixed some typos. Thanks for the heads up, Sonic_13!
