A Reddit member has posted the video of the upcoming PS4 firmware which adds tons of new features to the console. The video is about 8 minute long and tells you all that you need to know about the firmware.
Sony has started beta firmwares which means certain users can test the firmware before Sony deploys them for all PS4 users. There have been many new additions as the video shows and the most important one is obviously start/suspend function which was originally revealed during the PS4 announcement event.
Sony is doing a good job with these firmware updates but they have yet to catch Microsoft who have been releasing firmwares at a steady pace now and with a lot more worthwhile features.
