I think, for what it's worth the final breakdown for PS2 is something like this:
Globally: 155-157m?
US, Canada (50m ish for US & Canada), Western Europe, Australia (43m ish in W. Europe and Australia), and Japan (22m in JP) (115m-ish)
Continental Asia outside Japan (Hong Kong, Phillipines, South Korea Saudi Arabia, Singapore, Israel, China, Russia, etc) (20m)
Mexico (4m?), Central America (1m?), South America (10m?), Africa (2m?), Eastern & Central Europe (3m?) (20m)
We know that through the end of 2011, Sony had shipped 154.4m PS3s (they had shipped 150m through January 2011 via a press release after reaching 149.8m on the final day of 2010).
The forecast for that year (to March 2012) projected 4m PS2s shipped, and the demand had been falling 50% year over year each quarter. So I think it's reasonable to assume PS2 ended up at 156m or so globally.
