During Sony’s event in New York City, they announced that they plan to add second-screen app for PlayStation 4 that might be released in the holiday 2013.  There is no word about how much PS4 will be cost and what is the full hardware inside yet.  They also said that PS4 would allow gamers to try out new games before purchasing them.  Sony will be ready for a companion app called PlayStation App that will allow iOS and Android devices to become second screens for players. They informed that app could allow players to see maps on their second screens when playing an adventure game, purchase PS4 games while away from home and download it directly to their consoles at home, or they could use the app to remotely watch other gamers playing on their devices.
