System update 1.74 for the PlayStation 4 is currently available, but it's not very exciting.
It was basically just another stability update; not even worth writing about. However, the next update will give PS4 owners an additional much-requested feature.
As Sony wrote on Twitter , update 1.75 will add support for 3D Blu-Ray movies, and the best part is that it'll drop next week. This is a feature the PS3 has boasted since 2010 so one could argue that the new system is behind the times but hey, it's a new console and the manufacturer needs time to give it that fully-featured feel.
Update 1.70 added a new video editor, DualShock 4 light bar brightness settings and pre-load support, so the inclusion of 3D Blu-Ray movies might feel a little light in comparison. Still better than just a boring ol' stability update, though.
