Sony are pushing out a new PlayStation 3 firmware update, which - among the changes - supposedly "preps" the console for the upcoming addition of 3D stereoscopic gaming. PS3 3.30 System Software makes trophy sorting more straightforward, with new ways to view achievements, but the firmware supposedly brings with it an updated Terms of Service (TOS) agreement to which PS3 users must agree. Among the TOS changes are apparently permission for Sony to automatically update or change content, services and functionality on PS3 or PSP hardware, without requiring owner permission.
From time to time, it may become necessary for SCEA to provide certain content to you to ensure that Sony Online Services and content offered through Sony Online Services, your PlayStation 3 computer entertainment system, the PSP (PlayStation Portable) system or other SCEA-authorized hardware is functioning properly in accordance with SCEA guidelines.
Some content may be provided automatically without notice when you sign in. Such content may include automatic updates or upgrades which may change your current operating system, cause a loss of data or content or cause a loss of functionalities or utilities
The change, it's suggested, is being made to minimise future arguments such as those Sony encountered in removing the "Other OS" functionality in the last PS3 update. As for the 3D support, that's expected to be fully enabled in time for the first Sony 3D BRAVIA HDTVs arriving over the summer.
