Sales for PlayStation 2's notably aged hardware and software predictably went down. Unfortunately, it appears that demand for PSP hardware has dropped worldwide, resulting in approximately 3% less shipments this quarter (note that shipments and sales are two different figures). However, shipments for software have nearly doubled, reaching 9.1 million (an increase of 4.2 million).
While hardware may have seen a small dip, that software figure shows a still-impressive run for the PSP. It appears that the games division will be making most of its money from the PSP for now, as analysts predict that PS3 manufacturing costs will cost the company $2 billion within a year.
