Why can't some "official" from VGChartz reach out to Sony and ask for the final PS2 numbers? If Sony USA don't have them, it's no big deal for them to ask Sony Japan. I think, after so many years nobody at Sony will be butthurt. For them, it doesn't matter if the numbers are 156, 157, 158 or 162 mil. The PS2 is a MASSIVE success, so I don't see why they shouldn't reveal that number, if politely asked for.
