Sony’s official PlayStation.Blog has revealed that PSP firmware version 4.05 will be released shortly. Eric Lempel, director of PSN Operations, suggested that the update focused on the device’s music-playing capabilities:
"We know that more and more of you are listening to music on your PSP, and this update will add new visualizers for music playback, among other features."
Lempel stopped short of announcing those other features, but we should be able to find out for ourselves once the update is released. We expect that’ll be before Sony’s E3 press conference tomorrow, perhaps giving the company something to discuss during its keynote speech. Don’t forget, PSU will be providing up-to-the-minute coverage of everything PlayStation (and more) from E3 this week.
UPDATE:
As the comments below show, the firmware update is available for download!
