For some reason or another, the PlayStation 4 will not ship with the latest software installed upon it. For that, you'll have to download a 300mb patch to bring the system up to speed with version 1.50, which is set for a simultaneous release with the system's launch next month.
By updating the system software to version 1.50, you'll be able to experience what Sony calls a variety of new features in addition to the basic functions of the PlayStation 4.
Here's what's in store:
Remote Play
Second Screen
Record, take screenshots, and upload gameplay effortlessly
Broadcast and spectate gameplay
Play as you download
Multi log-in
Party (Voice chat)
Face recognition and voice commands
Background music player
