PS4 firmware update 4.70 detailed

This latest PlayStation 4 software update may have appeared out of nowhere, but we'd recommend not getting too excited. As many of you have already guessed, firmware 4.70 simply promises better stability and performance.

 It weighs in at around 340MB, and you'll need to download it in order to make use of your console's online functionality.   This isn't a big update to the system, but this just means that 5.0 is coming, and it will hopefully be another major updates chocked full of changes.
