PSN Update TOS Protects Sony from Lawsuits
Class Action Waiver. ANY DISPUTE RESOLUTION PROCEEDINGS, WHETHER IN ARBITRATION OR COURT, WILL BE CONDUCTED ONLY ON AN INDIVIDUAL BASIS AND NOT IN A CLASS OR REPRESENTATIVE ACTION OR AS A NAMED OR UNNAMED MEMBER IN A CLASS, CONSOLIDATED, REPRESENTATIVE OR PRIVATE ATTORNEY GENERAL ACTION, UNLESS BOTH YOU AND THE SONY ENTITY WITH WHICH YOU HAVE A DISPUTE SPECIFICALLY AGREE TO DO SO IN WRITING FOLLOWING INITIATION OF THE ARBITRATION."
As 1UP's Chris Pereira explains, the new TOS don't completely prevent you from filing a class action lawsuit. All you need is mail a letter to Sony, wait for them to lose it, send another one, and wait for their legal office to get back to you. Or, you can simply cancel your PSN account and file a lawsuit.
If you're already part of a summertime lawsuit that was filed before August 20, 2011, when all the hacks and information loss were happening, you're in the green, though.
Also, Sony is reportedly rebranding from Sony Network Entertainment America to Sony Network Entertainment International, which is also interesting, considering that the Sony Corporation is a Japan-based entity.
