According to a NeoGAF poster with a history of accurate leaked information from the NPD Group, Sony's PSPgo sold 100,000 units in October, with the black model outselling the white model two to one. As I reported last week, the PSP sold 174,600 units across all models. While some will say that the number is disappointing for this time of the year, it is an expensive system and the economy doth sucketh.
