Though Microsoft may be having its (VH1) Best Week Ever, Sony's PlayStation Portable had its worst. ChartTrack is reporting the PSP had its worst week of sales since its launch September 1, 2005. Both SCEE and ChartTrack blame the sales drop-off on the impending launch of the PSP-2000 model, coming September 14 (sans ceramic white) and believe the redesign will boost the PSP's sales.
Chart-Track did not provide specific numbers for either console's sales.
