You didn't really think that the PlayStation 4 would be nothing but a gaming console, did you? Sony took some time out of their E3 press conference to go over a few of the non-gaming features the PlayStation 4, Vita, and even PlayStation 3 will have.
On day one of the PlayStation 4's launch, it will have access to Video Unlimited, a service that will allow users to purchase or rent over 150,000 movies and TV shows. Whatever you buy or rent, you will have access to on your Vita as well. They were also very quick to mention that several of these movies/shows are exclusive to the PS4, which seemed to loudly say, "Not on the Xbox One."
Other movie services that are coming to both the PS4 and Vita are Redbox Instant and Flixster, both of which will go to the PS3 as well.
