Doctor_MG said: The idea that 10-15% of PS2 units aren't even accounted for and the real number is 170M or higher is, in my opinion, just way too farfetched of a claim. If true, why would that be the case for Playstation but not Nintendo anyway? |
I think Nintendo is very trustworthy with its numbers, as they even reported exact sales figures for the Wii U—even though they were terrible—and always provide numbers down to the second decimal place.
Sony's numbers, on the other hand, are inconsistent if you go through old (annual) reports and compare them with each other. This remains true even when considering that, starting from FY06 (ending March 31, 2007), Sony changed its reporting method from manufactured numbers to shipped numbers (= sell-in).
On Sony's Business Data & Sales homepage (https://sonyinteractive.com/en/our-company/business-data-sales/), they list "more than 160 million" as sell-in (= shipped), but it is unclear whether this number includes so-called unsold units, as Sony isn’t as trustworthy as Nintendo. The 160,636,885 figure refers to the number of units produced.
If we believe Sony and assume that the "more than 160 million" represents the true shipped numbers, then the 160,636,885 production figure must be incorrect—since it would imply that only 0.4% of units were demo, defective, broken, replacement, or spare parts. That can't be true!
