The US Playstation blog have recently put up their own frequently asked questions on the recent PSN network outage thats filled with tons of info, most of it we have already heard before. However, there is new part in the FAQ that wasn’t in yesterdays EU blog.
Q: When or how can I change my PlayStation Network password?
A: We are working on a new system software update that will require all users to change their password once PlayStation Network is restored. We will provide more details about the new update shortly.
This could mean that PSN will be offline for much longer, as system firmwares are extremely complicated and generally take a very long time to get ready for the market. We can probably expect PSN to come up next week at the earliest.
