A new firmware aka System Update 2.10 will be available tomorrow for the PlayStation 3 featuring the long-awaited DivX support. You will be able to play all your DivX encoded files with two exceptions. DivX 3.11 is not supported and files larger than 2GB cannot be played. Among other features, the firmware comes with a voice changer tool which allows you to change the tone of your voice during a voice or video chat and support for Blu-ray Disc Profile 1.1.
