The number of countries means shit all, the countries you mentioned make up the majority of console sales. I'm not saying Sony are lying, they can't unless they want to get fucked over like good ol' Tesco were. Just curious to see which countries outside the ones you mentioned make up the console sales.
It's missing the UK, which is likely 1.5M if not more.
Canada is traditionally 10% of the US market, then there's Australia, etc. It adds up fast, even if we're talking 100k per country on average.
