Patrick Seybold, Sr. Director, Corporate Communications & Social Media says the move was made "due to security concerns."
Seybold says the update is optional but if users choose not to update they will lose:
* Ability to sign in to PlayStation Network and use network features that require signing in to PlayStation Network, such as online features of PS3 games and chat
* Playback of PS3 software titles or Blu-ray Disc videos that require PS3 system software version 3.21 or later
* Playback of copyright-protected videos that are stored on a media server (when DTCP-IP is enabled under Settings)
* Use of new features and improvements that are available on PS3 system software 3.21 or later
That means the update is pretty much required more than "optional."
