The PlayStation Store is officially restored! Complete with a massive catalog update ranging from premium content for PlayStation Plus members as well as plenty of demos, add-on content and goodies for the rest of the community.
The Welcome Back programme has yet to kick off, PlayStation Store director Grace Chen notes that it is still in its final stages of testing and will be available as soon as possible. You can expect yet another store update come Friday this week.
For the full list of updates and additions to the store, check out the PlayStation Blog. 'Whopping' does not begin to describe that list.
And just as a heads up, it seems like the servers are quite strained at the moment, likely due to the massive influx of traffic.
