As soon as consumers hook up their brand new PlayStation 4 at home, they will have to update their new console to Version 1.5, which will add many of the features that have been hyped by Sony.
The update comes in at an estimated 300MB and will add support for many new functions, including Remote Play and Second Screen through PS4 Link, recording, taking screenshots, uploading, broadcasting and spectating gameplay, the ability to play as you download, multiple log-ins, party voice chat, face recognition and voice commands. Support for background music during gameplay, online multiplayer and Blu-ray Disc and DVD playback will also be added through this update.
A few other important features such as the power saving suspend/resume mode will not be added at launch. These features will be added at a later date.
While day one updates are to be expected these days, a 300MB update does seem pretty big, and those with poor online connections or no internet access will sadly be missing out on many important features.
