Sony believes the Playstation3 will ultimately outsell the PS2
So far, the PS2 (released in 2000) has been sold over 140 million times world wide. The Playstation 3 made its debut in America and Japan in 2006 and found 14.27 million buyers worldwide after 20 months. However, in order to fulfill Hirai’s dreams Sony would have to sell almost exactly this many units every 12 months over the next 7 years.
