Sony doesnt track sales .Thats why they use the information that the agencies that they have contrated to receive information for their businees .Agencies as NPD ,GFk ,Gamecharts ,Media Create etc .Thats why we should listen when they give data .
And this information confirms my fears abou the PSP ,its way undertracked in this site .The total tally must be close to 25 million now .
