If you happen to be visiting the PlayStation Blog on a weekly, daily, or hourly basis you will have likely seen the following message.
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.
We’re right there with you. At this point any and all PlayStation 3 games we’re reviewing will be reviewed without online multiplayer because we can’t afford to delay our reviews by weeks, or perhaps even months. Sure we do this from time to time, but if we can prevent it, we prefer to get you reviews as soon as possible.
I’m fairly certain the PlayStation Network will be back online before June 1st, but anything outside of that is a guessing game.
