No, we're not finally getting SharePlay and the other cool new features which are being promised for PS4 update 2.0 but users will notice their box getting yet another update today.
Firmware version 1.76 is currently rolling out and the main information we have suggests its bringing... improved system stability. Again. For a console that doesn't seem especially unstable, the PS4 sure does get a lot of stability updates.
It's a big enough download - 200 megs or so - and you won't be able to use the console online until you get it. So prepare for yet another update next time you turn on your PS4. Let's hope we start getting some actual content again soon.
The version 2.0 update will bring a new feature called SharePlay which essentially allows you to let your online friend jump in and help with your game, among other features. Expect that in the next couple of months.
