As promised Sony launched today the new Playstation store and released the latest firmware 2.30 for the PS3.

The big news in the Sony PS3 firmware 2.30 is the support for Blu-ray Disc DTS-HD audio. DTS-HD can deliver audio that is bit-for-bit identical to the studio master at high variable bit rates. The codec can deliver up to 7.1 audio at 96k/24-bit.
In two days the Sony Playstation store will see some new exciting content. Sony will offer Metal Gear Online Premiere Beta. Also available will be Warhawk: Operation Broken Mirror, a great new addition to the Warhawk experience and Lair: Diabolical Dragons Pack and Skyguard Upgrade pack, offering new features and functions.
There will also be a collection of trailers including the latest for GTA IV, as well as a Sega Superstars tennis demo.
