PS3 firmware v2.80 available now
Eric Lempel, Director of PlayStation Network Operations, has confirmed the previously rumored firmware update, PS3 firmware v2.80, on the U.S. PlayStation Blog.
"The playback quality of some PlayStation 3 format software has been improved [in v2.80]," states Lempel.
Currently, the update is available on the PlayStation Network, but not mandatory. If you turn on your PS3, you will not be prompted to download the firmware update, but if you manually navigate to and click 'System Update,' you should be able to view and download firmware v2.80.
Users are reporting faster access to Trophy data and general improvements to XMB load times after installing the update.
