The PS4 is now officially launched, and a couple of the neat features it has can be enjoyed if you have a Vita:
Play almost any PS4 game in the palm of your hand! Using Gaikai streaming tech in part, you can send a game signal from your PS4 directly to the Vita via built in, advanced WiFi tech (compared to PS3 / PSP) , or your through router via your WiFi signal, or through the internet, or even through your 4G mobile phone connection to a registered Vita and get a pretty good experience on Sony's handheld.
Of course the direct method works best when you have your PS4's internet connection hard wired, especially if you stay in range of the two units for the best signal. Lag is almost imperceptible in the best of conditions, and the Vita's stunning OLED screen makes it all look fantastic. The controls are modified on a case by case basis, but games generally feel about the same. One bummer however - 30fps is the max output to the Vita as of now. Hopefully the cap gets lifted in the future.
Here's a Remote Play how-to guide to get you going. It's also been said that you should turn off WiFi Power Save Settings in your Vita (last system menu option, by default its turned on).
As a bonus, the guide also points out you can use your mobile phone as a companion app to do some basic PS4 UI stuff (like check messages, dload and install content, etc.) while away from the console. Here's the link to the iPhone app, and here is the Android app.
Games can be designed to use the Vita as a controller, replacing the DualShock 4, to make use of it as a second screen. On the PS3 we enjoyed this feature in Guacamelee (as an always-available map viewer),. It was also available in a short LittleBigPlanet 2 spinoff title where the game switched back and forth between the two screens, allowing the gamer to use some of the Vita's custom control features to conquer levels in ways not possible with the DS3 alone (PS3 video of it in action). With Remote Play convincing some players to get a Vita, we may see more Second Screen content in the future on the PS4.
