Ah, I love watching these things. I think it's clear, no matter how much people want to slate it, that PSVR will do very well or itself. It is a full on complete VR system that can induce presence, the same way Rift and the Vive are. The differences between them reflect the age old console vs PC differences.
One offers higher fidelity but doesn't particularly offer anything that simply could not be done on the former. Many of the Rift/Vive games are being co developed for PSVR as well, games like Eve Valkyrie or The Assembly. All systems will have their own exclusives, and signs point to PSVR having the biggest name exclusives off the bat. GT sport and very possibly No Man's Sky (BIG IF on that one but there's evidence that something has been happening behind the scenes on it, this isn't completely pie in the sky thinking before I get shot down!).
PSVR offers presence inducing, high framerate, plug and play VR that compares with Rift and Vive, which will come in at 2 or 3 times the cost when the high spec PC needed to run them is factored in.
Also, there's going to be millions of people wakened up to VR this year, indeed next month, when they get their new S7 phones and free Gear VR. When they look into more impressive VR offerings PS4 and PSVR will be easily the most attractive option out there, long before PCVR becomes remotely affordable to most of those people. I see it doing really well.
As for porn. I think Sony need to perhaps work on this. Have a separate part of the store password locked that needs to be set up externally, via a website and confirming ID via Credit Card or something. I think they need to offer VR porn because 1. It will make them a shit load of money, 2. It will stem the tide of people choosing PC VR over PSVR for this feature alone 3. If all PCVR solutions can work with it, Sony sell 18 rated games and films on their service, then really what is the difference? Just make it a bit of a hassle to register to use it, make sure it's password protected behind a credit card or something so kids have less chance of getting into it, et voila! PSVR sells 100 million units!
