routine scheduled maintenance. We have confirmed with Sony that this is not the PS3 v2.4 update, which will add in-game XMB and trophies.
During the maintenance there will be no access to the PlayStation Store or online play through the PSN. Those who had online plans, feel free to take the opportunity to catch up on your Joystiq reading, we've got plenty of features to burn six hours on.
