David Perry has announced that you'll be able to try PS4 games from the cloud straight from the PlayStation Store.
In addition to the above, you'll also be able to share video and share to Facebook. There will also be a new look dashboard to accommodate this.
As for non-gaming, players will be able to spectate other and even jump in and help. You'll also be able to broadcast your games using Ustream.
Perhaps even more exciting for PS Vita owners is that you'll now be able to use remote play to stream PS4 games to the handheld. Sony says that it's long term goal is to make every game playable on the PS Vita, while also allowing gamers to play live PS4 demos on the PS Vita too.
As you'd expect, service such as Netflix, LoveFilm and more will also be coming to PS4.
