First Screenshots from the Playstation 4 User Interface
The images looks like the user interface Sony showed at its recent event in New York City, and depict the user home page, which lists your friends, trophies, feed, and shared media as well as add-on content.
There's also a profile page and a shared content page that shows how PS4 owners will share content with their friends. The screens also provide insight as to how the sharing process might work, including a Trim Video editing feature.
