It’s been confirmed that the next system software update and PSN Store update will take place on April 14th, just in time for those of us rushing to file our US Income Tax returns to be forced to take a break and try to track down that receipt for that business dinner at the "Thirsty Alligator House of BBQ".
According to playstation.custhelp.com, the PSN store will be upgraded and inaccessible from April 14th at 8:00 am Pacific Standard Time and available again at 11:00 PM that evening. The entire PSN will be unavailable as well during this time frame. Once the PSN is back up and running, a new software upgrade will be available and will be required to use the PSN.
Once you get the update and check out the store, please check back and tell us your thoughts.
