Starting September 15, the PlayStation Store will no longer be accessible for PlayStation Portable (PSP) users in several regions, including Europe, Oceania, Asia, and some parts of Africa.
A Sony representative told IGN that PSP users in these regions will still be able to purchase content for the handheld device through the Sony Entertainment Network Online Store, and past purchases can still be re-downloaded from the download list on the systems.
At this time, North American PSP users will still have access to the PlayStation Store as Sony continues to "evaluate market trends" in order to determine what is best for all other regions.
