Sony has been crowing about the PlayStation 4 and PS Vitas love affair since last February, and with the latters latest software update Hirai and pals are making good on those promises. Perhaps its most important feature is the PS4 Link, which acts as a sort of wireless umbilical cord between the next-gen console and the portable. PS4 Link allows certain PS4 games to be played on the Vita, and it turns the handheld into a second screen for some titles as well.
