Depends on how impressive it is and how cheap they can get it bundled with hardware. I think if you sold it as a all in one box (console/add-on) for 600 dollars, it would sell to people that really wanted Oculus Rift to be 350ish.
Think about it, with Oculus Rift you're paying 600 just for the head hardware, you still need a good enough PC to run the thing. I think the PSVR might be a worse experience but thats just how it goes with PC vs Console. PC's always have beefy hardware. But people still buy console games cuz their hassle free. IF someone wants to get a VR set up and they don't want all that tech mumbo jumbo of making a PC for over 800 bucks then getting a 600 dollar headset. PSVR is less hassle and cheaper.
Expect there to be kiosks at all retailers before it launches. They say you have to fully experience VR to appreciate it... we shall see if the public agrees.
