Firmware update 3.70 will allow subscribers to automatically upload their game saves to the cloud under the 'Automatic Update' option in the system settings.
The option will also enable automatic downloads for future firmware updates as well as instant syncing of Trophies.
Previously, PlayStation Plus subscribers had to manually upload game saves from the XMB, while Trophies would sync irregularly.
Elsewhere, a new category on the XMB will be devoted to TV / Video Services, and will house applications such as BBC iPlayer, 4OD, Netflix and Hulu Plus.
Finally, Blu-ray movies will see enhanced 3D support, with Java-based features, more audio options and digital photos in MPO format now available.
Xbox 360 will add cloud storage to game saves and user profiles later this year.
Firmware update 3.70, as well as PSP update 6.60, will be available soon.
