Found more evidence that the PS2 - "140m" in August claim is bogus:
http://www.sony.net/SonyInfo/IR/financial/ar/2008/qfhh7c00000htn6x-att/SonyAR08-E.pdf
Its on page 33 (the report deals with FY 2007 which ended March 2008, even though it is called 'Annual Report 2008' on page 1)
"PS2 cumulative sales (sales to stores) reached approximately 130 million units" in March 2008 (page six confirms the date)
"PSP cumulative sales (sales to stores) surpassed 37 million units" in March 2008
Sony then lists cumulative sales (sales to stores) for Q1 and Q2 FY 2008 here (which is through Sept 2008):
PS2 - 1.51 + 2.50
PSP - 3.72 + 3.18
That means that as of September 2008 Sony has shipped:
"Approximately" 134 million PS2s
At least 43.9m PSPs.
Those figures tie in well with BKK2's figures - 133.8m PS2s as of September 2008, and 44.5m PSPs
