Given whats been shows it might just be a big part of gaming, eve valkyrie looks good enough to me that i dont think more power of a new gen down the line is really needed. While Kinetic on 360 has shown just how succesfull an addon can be, i beleive theres much more support in gaming for vr then there ever was for waggle.
I dont think standard equipment is needed, those that want will get it those that dont save $. All that is needed is one killer app that cant be done on a regular console tv experience to light a fire under peoples ass's. Will take just one FPS to do that in NA while Europe is easy enough for Sony. GT7 VR edition, ill pay whatever to get that and Vr success guarenteed on the old continent.
Yes, but don't forget that here on this site we're all more dedicated to gaming than average, what can persuade us won't be enough for other people. And even amongst us, power whores could find meh a 1080p display for VR helmets, as 1080p is fine for a display, viewed from a distance and occupying a few tens degrees of our field of view, but it becomes mid definition in a helmet, where it occupies almost the whole field of view. Also, for prolonged use, high refresh rate and fps, extremely comfortable design and materials and very low weight, will be of the essence, tech won't arrive to that levels, and at mainstream prices too, in short times (casuals will want these high performances and specs purely for comfort of use, unlike power whores, but different causes will have the same effect on adoption of the new tech).
Don't forget that even 20 years ago VR had become the latest tech fad, but tech not mature and cheap enough yet ended up stopping the attempts quickly and delaying successive ones to relaunch it as mainstream by two decennia, while in limited fields, mainly scientific and industrial ones, but also very small niche games and entertainment apps, research, development and use has continued and increased quite steadily, but remaining of limited size anyway.
Standard equipment could be not necessary if VR will be at least available as option on enough platforms to make the total user base large enough, but, again, just one killer up could be good to start, but it will have to be followed up by a regular stream of releases to last and not fade away again.
This said, commitment by both Sony and OR, and probably some less known projects too, is good news, the wider the efforts, the sooner the critical mass, at least for the first phase, could be reached. A far larger gaming and computing overall market than 20 years ago will help a lot too, a 10% niche now (including console gamers plus even just those 100 million more hardcore than average PC gamers and not including the other 300 million casual ones) could be larger than a hefty 40% market share back then.
