The features that will be temporarily disabled are What’s New and Content Information Screen. What’s New lets you discover and engage with your friends’ PS4-related activities. The Content Information Screen lets you see friends’ activities and information specific to the title you are looking at.
These aren’t exactly what one might deem “essential features”, but if you are bummed out about these not working, don’t worry. Sony will be bringing these features back online shortly after the massive influx of players that will try logging in to PSN. All other PSN-related features of the console will work just fine, including the ability to play online multiplayer games, get trophies, add friends to your friend’s list and share videos and live broadcasts of your games.
It will be interesting to see how the PS4 fares in Europe, especially since the Xbox One is already out. Last week, Sony had revealed that the company sold more than 1 million units of the console in the first day of its North America launch. Note: this isn’t 1 million units sold to retailers, but in fact, 1 million units in the hands of customers. Microsoft announced similar figures, but it launched in a larger number of countries at once.
