@Shikamo To be fair, we know that PS1 sold 102.49m and PS3 sold 87.40m, but Sony put "over 102m" for PS1 and "over 87m" for PS3. With that in mind, I'd imagine that it is safe to say PS2 is somewhere over 160m but still less than 161m. The PSP stating "over 80m" might be of lesser importance because it is in smaller text (I believe it was already confirmed that the PSP outsold the GBA's 81.51m).
