We are getting used to posting these words now, but Sony has just sent official word that they will be able to provide details of the restoration of PSN in “at least a few more days”.
Here is the latest update from SCEA’s Patrick Seybold:
I know you all want to know exactly when the services will be restored. At this time, I can’t give you an exact date, as it will likely be at least a few more days. We’re terribly sorry for the inconvenience and appreciate your patience as we work through this process.
Hopefully we will start to see some services back very soon.
