So, it seems we all get the new PSN Store next week. In a press release, Sony made official that the update will be made available on the evening of April 15th in Japan, which will come with the v2.30 firmware update.
According to the Playstation Blog, the US will be getting it in mid April, but Grace Chen, in a video about the update, mentioned that GT5 Prologue would be available on April 17th on the PSN Store. Since Sony said no new downloads would be available until the Store was re-launched, I believe this means we get the update next week too. Here’s a video of the features and the slipped relaunch date.
