One thing to consider is that in September Sony announced that (something like) 22 Million PSPs were shipped worldwide and currently VGCharts has the number of PSP systems sold at 20.75 Million ... Now I suspect that Sony has continued to ship as many units as they can get away with so many retailers have full inventory and Sony is (probably) trying to ship more. Retailers (generally speaking) don't like having large inventories of products that will last them 1 or 2 years (at current sales) because it costs them money and takes space away from products that are in demand.
