They disappeared after a couple of weeks (it was only ever a popup shop), so I don't know if interest trailed off or not. (I never got around to playing it myself either.) But considering many of the VR games sell for just $5, it made me feel the money right now is in running the VR arcade, not developing the software for it!
Many people go to retail locations only to confirm details for later online purchases. This is already happening and has a name - "showrooming".
VR will close this gap by bringing the retail location TO the home.
For example: I don't buy clothes online because it's important to see how they fit on me specifically before pulling the trigger. VR that could do this sufficiently well would totally end my shopping at physical retail locations.
Rephrased as "VR shopping will be a larger market than living room entertainment", it's a more plausible/even discussion and I don't have as strong an opinion.
Hate to burst your bubble, but quality control from mass market clothing brands is going to keep this from becoming reality. Levi's, for example can vary several inches between garments of the same listed size.
Really hoping the Magic Leap augmented reality experience matches the hype.
