The 1.92 firmware update hit PS3s earlier today. Here are the features:
"Playability status with the PS3TM system has changed for some PLAYSTATION®3 format titles*."
This is according to the official press release on the UK PlayStation site
Sadly, this doesn't affect the Middle East, Europe, or Oceania.
Great update then. Anyway, now that 1.92 is out of the water, the next update could be 2.00 (big jumps in version number have occured before).
Hopefully not only will it arrive with PlayStation Home, the 3D social networking environment, but also an in-game cross media bar.
Stay tuned to PSU for more firmware update related information.
