Sony has just unveiled its latest metrics data for PlayStation hardware and software sales worldwide. Of particular note to avid observers of the handheld console wars is NPD's data on "portable hardware dollars market share" for the calendar year 2006. According to the data (seen above), Sony's PSP system actually beats Nintendo DS by a fraction of a percentage. This makes sense, considering PSP's significantly higher asking price. Although DS clearly has far more units in households, this kind of data proves that Sony isn't out of the game.
