When Sony released version 4.45 of the firmware for the PlayStation 3 a few days ago, thousands of users reported having problems with their systems. The firmware, which was only intended to add trophy notification options and improve overall system stability had ironically "bricked" their consoles.
Sony is aware of the issue, and has since issued a statement on its Japanese PlayStation website stating that a fix is on the way for release on June 27 for all affected PlayStation 3 units.
Here's Google Translate:
“Notice of 4.45 delivery PlayStation ® 3 system software version (6/21 update)
Person from some users that were conducted to update to system software version 4.45 of “PlayStation 3″, we have received reports XMB (cross media bar) will not appear after the update, but new to solve this phenomenon will be published on Thursday, June 27, the system software updates such. For now put everyone in a user, We apologize for the inconvenience, I would like to ask for your understanding. PlayStation ® 3 System Software Update”
It's not known when the US and international owners of the PS3 will see the fix, but it shouldn't be too long after Japan gets theirs—if not on the same day itself.
Update: The European PlayStation account on Twitter has posted a similar update, announcing that affected consoles will be fixed on June 27.
