While i personally love consoles for the standard that they give to games, in terms of hardware, which in turn gives us less buggy games, your argument is , again, flawed, because that risk of the pc not being good enough to run Rift will not be big of an issue to people, those who bought the rift, the same way that pc games never has been a issue to most gamers.Has PC games sold poorly because if you dont have a good pc, you cant play it?The fact is, even with these restrictions, that every 2 or 3 years you need to spend 300 to 400 dollars to upgrade your pc for it to run pc games at a good framerate, graphics, etc, games on pc have been increasing in sales and gaming in pc has been regaining popularity.So while saying that the PS VR will be more "stable" is true, the meleability of the PC will not and never was an hidrance for Rift.

And yes, more powerful does not mean more sales, and yes software is king.But the Oculus IS receiving great support from games.And it has one thing that PS VR lacks and what I think it will be fundamental to shape VR in the future:Other applications outside gaming.That gigantic advantage will make Rift much more desirable than the PSVR.The only thing that makes things even betwenn the two are the price, but that will go down with time(VR wont make Mainstream for many many years in my opinion).And if the PSVR remains just for gaming when the price goes down, well, it will not be able to compete with the rift.

And yes, the big appeal of the VR is the new experience.But as new as it can be, if the applications are limited, and most importantly, the price is too high, people wont buy it, no matter how inovative it is

I don't think it will be much of an argument to the people who actually end up buying the rift, but will lead to a number of people on the fence who are the same people who are not confortable with pc gaming choosing not to go with the rift but the PSVR. 

While PC gaming has also been growing over the years so has the core console gaming audience. 

When it comes to software between the Oculus and PSVR they are relatively even, but the lower cost to entry for the PSVR (which I am guessing at this point) and PS4 relative to a high end pc and name brand recognition will likely mean high sales in the beginning that will boost software support for the PSVR and lead into more hardware sales. 

I agree that VR won't go mainstream for a while due to it being an unknown quantity but that's all the more reason that a lower price and name brand recognition will make that initial investment less of a risk. If the PSVR focuses solely on gaming it will find itself to be more of a niche gaming console and the Oculus will have the edge in the long run but I believe that Sony has learned from the PS3/PS4 the importance of social media and will make a strong push with the PSVR.
