It dosnt matter if it has an huge installed base, if the interest isnt simply there.You need to remeber that the PS4 is the popular console of this generation.That means that most gamers there are casuals, and casuals will not be willing to spend around 400 more on a pheriperal that will have little use, and even little number of games that truly use it in a really good way.Plus the PS VR, while cheaper, is limited to the PS4(as far as i know), while the Oculus Rift is more brand in use, even if it way more expensive.
That is my theory, but i believe that Sony knows that VR wont take off now, in which i mean they are expecting 500k to 1 million units sold in a year time frame(around that anyway).I believe this is a long time investment, to get people accustomed to VR and market it for future generations, so that it becomes a easier sell later on.
My (locked) thread about how difficulty should be a decision for the developers, not the gamers.
