There is no way to know for sure. Also companies do not say they sold 1 million at 1,000,001 units sold they wait until 1.1-3 million so they are sure they are correct. But as I said there is no way to know for a fact

Sorry dear but there is...http://web.archive.org/web/20110703164827/http://scei.co.jp/corporate/data/bizdataps_e.html

The 102.49 figure is right,ps1 is overtracked here!:P

How is that proof? Do you really think Sony knows exactly how many are produced? That is an estimate or do you believe EXACTLY 102.49 million were produced?
