The rumors are true: Sony's working on virtual reality. The hardware is called "Project Morpheus" and it's headed to the PlayStation 4. The headset is two pieces: a closed display and what looks like a PlayStation Move sensor built in. SCE Worldwide Studios head Shuhei Yoshida unveiled it on-stage tonight at GDC 2014; he said the "prototype" is "by no means final." It's the culmination of over three years of work, Yoshida said, and the prototype unveiled tonight will also double as a dev kit.
