For the fourth time, Nintendo raised its sales and profit forecast for the business year that ended March 31, mainly thanks to high demand for its DS titles, as well as the Wii console. Sales were up 7% ($8.1 billion) compared to last year, beating analysts' expected 3% increase. In the past business year, eight of the 10 best-selling games in Japan were DS titles. In February, Nintendo sold more than twice as many Wii's in Japan and the U.S. than Sony's PS3. Stock prices rose 2%, nearly doubling in value over the last 12 months.
