According to David Mercer, principal analyst at Strategy Analytics, Sony's PS3 will sell more units than its rivals the Xbox 360 and Wii over the lifetime of the current hardware generation.
A report titled "Taming the Waves: Games Console Life Cycles and Platform Competition," predicts that the PS3 will remain a commercial platform five years after the Wii has been replaced, with lifetime sales predicted to reach 127 million units, compared to 103 million Wii units.
"Nintendo has done a great job with the Wii in bringing console games to new audiences," said Mercer. "But its sales are now falling, particularly in mature markets, and its installed base will peak in 2011. Ownership of both the PS3 and the Xbox 360 will hit their highest points between 2012 and 2014."
In 2010 the report predicts global Wii sales of 17.5 million units, the PS3 14 million and Xbox 360 10.5 million.
