As mentioned in my older post, Sony today released their latest PS3 firmware version 2.3 with support for DTS-HD audio. The latest firmware was released along with updated and redesigned PlayStation Store. With the redesign of the store it’s easier to find add-ons, games, video and other content. Gamers can also see the video preview and pictures before downloading content. Now the shopping bag (cart) will let users track the purchase history.  The upgrade is free for existing PS3 user and coincides with the launch of GT5 Prologue, which is available for download through online store.
