When asked whether or not PlayStation fans can expect future iterations of PSVR, Layden told IGN, "we are constantly iterating and innovating our hardware almost the minute that [we] delivered the first," citing Sony's 21-year history of continually improving the PlayStation platform."When you deliver unit 'A,' you know 'A Prime' is already in design," the Sony exec explained. "You can look at the first generation of the product and see the future about where you want to go," he added, highlighting the fact that "there are certain technologies that we need to incorporate" as well as "certain technologies that don't exist yet."As such, Layden said Sony is approaching the launch of PlayStation VR as "step one in a very long journey," adding, "We're all in. We've put it all on the table and I like our chances."Sony's foray into virtual reality officially begins next week, when PlayStation VR launches on October 13.
