If you look at this PDF from SONY, you can see that they say the PS2 has sold 136 million units as of December 2008.

P.S. YOU HAVE TO READ THE ASTERISK THAT IS AFTER THE SENTENCE THAT GIVES THE SALES TO SEE THE DECEMBER FACT, I DIDNT MAKE IT UP.
P.P.S So just over 136 as of December, anyone care to make a guess as to what it is at this very day?
