The PlayStation 3 is getting a new system software update (v4.20) tomorrow, and with it comes some minor updates to strengthen functionality and improve the experience. The last software update (v4.10) added a feature that enabled you to hear your own voice through the wireless stereo headset when playing multiplayer modes, known as sidetone. The new system software update will improve sidetone audio performance by giving options to select on out of five levels for microphone audio. You can also simply turn off the feature.
The update also allows those using the headset to watch Blu-ray or DVD movies on your PS3 to use virtual surround sound functionality for superior audio quality.
You can set the amount of time that the system will wait before turning itself off automatically for [Video/TV/Music/Photo] and for [Game/Other Features]. Saved data management has also been improved and you will be able to select multiple saved data items and delete or copy them as a group.
Look for the software update tomorrow.
