Vgchartz shows 123 million, wikipedia shows 140 million http://en.wikipedia.org/wiki/PlayStation_2

which is most likely?

I think Kaz Hirai himself recently said it was around 130 million.

Wikipedia isn't the most reliable source, as it can be edited by anyone

Either way it is some amount of consoles sold.
They could keep it going another couple of years.

Sony themselves are the source for 140mill. I suppose that's more likely.

Jacob has already debunked the 140m number.

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

Wikipedia is not a reeliable source by any means, honestly the data is 50% bullshit, 15% hearsay, 25% propaganda and 10% truth.

Seriously, do yourself a favor, never rely on wikipedia because it is all crap. Vgchartz is he most likely reliable source by a long way.

sony stated that is above 130 million.

In fact I have proof that wikipedia is unreliable. This link is for wikipedia page on lithium nitride, most of the stuff on this page is unreferenced and the stuff that is referenced often leads to sources I would never put in a report for university. How do I know? I wrote it.

In fact If I recall one of the links doesn't lead anywhere.

I know its not reliable. Only because the number is taken from an offical sony quote did i take it seriously. Also this number has been there for ages.

good luck for 3rd in the league by the way!
