Sony Targeting ‘Experiential Marketing’ for PlayStation VR
Sony Interactive Entertainment will offer in-store demos of PlayStation VR beginning this June.
It’s often said that modern virtual reality (VR) has to be experienced to be fully understood. It now seems that Sony Interactive Entertainment (SIE) feel the same way, as the head-mounted display (HMD) manufacturer intends on offering 500,000 demo stations to retail partners across North America.
SIE Vice President of Marketing, John Koller, presented at a Gamestop investors meeting last week, stating that “Trial drives the conversion to purchase… We’ll have a fantastic technology, but you need to get your hands on it.”

And since Gamestop is just one of the retail partners , and it has done good there, that still leaves a sizable retail partner presence for the rest of the PSVR demo units..Bestbuy..etc
Since the demo test units is still PSVR units in the retail market even for demo's that's still 500,000 manufacturered PSVR headsets Sony has made sofar ..that's a lot..how many past that for retail ? 1 million total so 500,000 for launch or more?
Still 500,000 PSVR units already produced it a lot just for demo station purposes.
