The PlayStation Network will go offline for several hours today in order to prepare the launch of the new PlayStation Store for tomorrow. The store will be offline from 8:00 AM PST (4:00 PM BST) until 11:00 PM PST tonight (7:00AM BST tomorrow). The announcement notes that other PlayStation Network services will not be affected. Before you can access the new store tomorrow, you will need to download firmware 2.30 when it is released tomorrow.
We will bring you more information on firmware 2.30 and the new store tomorrow. Sony has already confirmed that firmware 2.30 will include DTS-HD Master Audio and DTS-HD High Resolution Audio features for Blu-ray movies, but other changes in the system software are still to be determined.
