I dunno how many of you have PS3s or have heard about this but hackers broke into Sony's "stuff" and now all our info has been stolen. I just went through and changed the pass for any accounts that shared my PSN pass, probably a good idea for anyone that hasn't done so.
This hasn't been confirmed. No one knows for sure whether the hackers have anyone's account details, but it is a good idea to change as much of it as possible. The PSN network is expected to be up and running as normal tomorrow.
