Sony has announced it will be releasing a new firmware update for its PlayStation 3 games console.
The update, v3.40, scheduled for release on 29 June, will add a number of new features, including a cross-game voice chat platform.
Digital Spy reports that users will be required to install the update before they can start using Sony's new PlayStation Plus premium service.
In a statement, the company said: “PlayStation users can purchase PlayStation Plus membership through PlayStation Store on PS3 only. Users need to install PS3 system software version 3.40, which will be released on June 29, to enjoy PlayStation Plus.”
Also at E3 this week, Sony announced the introduction of 3D games on the PlayStation 3, and the launch of its new motion-sensing controller, PlayStation Move.
