Throughout the PlayStation 4 announcement earlier today, Sony kept going on about how there would be a mobile component to the PS4, but unfortunately it seems like all the good stuff will be put towards Sony's less-than-successful PlayStation Vita. There was no mention of expanding the PlayStation Mobile
program and bring games to more mobile devices, but there was an announcement of a new PlayStation app for iOS and Android which will act as a 2nd screen for your games.
The idea is that the PlayStation app will be made available for iOS and Android and it will offer in-game maps, social networking tools, or an easier way to access the PlayStation Store to buy a game while you're away from home and have it automatically download so you can play when you get back. Basically, the app will make your mobile device into something like the Wii U GamePad rather than something that can legitimately play full games on the go.
It's a start at least, and maybe if the Vita doesn't pick up steam Sony will change the way the app works and start bringing games to more mobile devices, but obviously it will try to push the Vita first. There was no word on when the app or the PS4 is planned for release, but the smart money says that the console is probably going to be coming in time for the holidays, so we'd expect the app around the same time.
