Virtual reality buzz has waned at E3

Virtual reality handsets were virtually everywhere at last year's Electronic Entertainment Expo (E3).This year, despite vr-related exhibitors increasing, the buzz surrounding the immersive technology has waned.According to the entertainment software association, which organises E3, 126 exhibitors at this year's event are involved in the VR, augmented reality and mixed reality space. That's a 138 percent increase from last year. Sony Playstation says it has sold over one million of its vr headsets since the device launched last October. Despite that, much of its booth is dedicated to traditional console games.
