Sony has released firmware version 2.30 for the Playstation 3. DTS-HD Master Audio and DTS-HD High Resolution Audio outputs are now supported when playing back Blu Ray disks - however it does not yet support DTS-ES and DTS 96/24 for DVD-Video or DTS-ES Matrix. You can update to the latest release via System Update or download the 130MB package via a computer.
Oh and the update allows access to the redesigned Playstation Store. I haven't updated yet and of now but there will probably be some new content added during the rebuild. If anyone spot anything new, please tell and post via comments.
