Sony's latest PlayStation incarnation, the PlayStation 3, has not faired nearly as well as its predecessors. Nintendo's resurgence with the innovative Wii, targeting casual gamers, loomed in stark contrast to Sony's PS1 business model. Of the three major consoles competing today, the Wii dominates with more than 55% of worldwide console sales, while the Xbox 360 claims nearly 25% market share, and the PS3 has slipped under 20%. Nintendo sold 10.17 million Wii systems in 2008, along with 9.95 million handheld DS units, and is expected to cash in on its DSi system, set to be released in April.
