PS3 firmware update 2.5 will add special support for the official PS3 Bluetooth headset, such as on-screen volume, battery and mute indicators, as well as a "high quality" mode; in-game screenshot capture (for supporting games in the future); and an improved Trophy system featuring new options to compare Trophies with other players.
The major feature coming with PSP firmware update 5.00 is the previously-announed ability to connect directly to the PlayStation Store, eliminating the need to connect the PSP to a PS3 or PC to download content to the handheld.
Also added with the PSP update is an on-screen QWERTY keyboard, a sleep timer for music playback and improved video-out for the PSP-2000, allowing PlayStation titles to be displayed full screen on home televisions.
