i think 2016 proves that Sony will have content available whether they have direct control over it or not. X1 games being delayed is a non-issue for Sony at this point. It just means they have better opportunity for success in 2016 which is really all they need. MS having a strong 2017 is almost an irrelevant point at this stage of the gen. Good for X1 owners of course.
And I think ppl are overselling the EXPERIENCE part of VR if you think that alone is going to sell a potetnailly $400 product. VR is an awesome experience but I aint throwing that kind of money at a device that is going to have tons of experiences that can be played without it.
the VR experience + games that need a VR device is what it going to sell an additional peripheral on top of having a PS4. You need a PS4 for PSVR, having VR games become compatible for non-VR users is not going to make a noticeable bump in hardware sales.
It might be a none issue if Sony were competing with MS but they're not now and have stated as much. They're now in competition with the PS2 and they'll do everything in their power to make sure people opt for a PS4. If there's a month when the XB1 has a big game and the PS4 doesn't, it makes sense to make sure PS4 owners have something to play and the media have something to talk about. Regardless though, PSVR has given Sony an opportunity to bolster their portfolio of games for the vanilla PS4. The fact No Man's Sjy is likely going to get a VR version in no way will impact the vanilla PS4 version. The only likely outcome is that those with No Man's Sky already might decide to buy the PSVR later on when they can afford it.
The PS5 Exists.
