I think head-mounted-display virtual reality is a huge missed opportunity for next-gen consoles. They could have really done it right in a way that PCs can't yet, with special hardware support for low latency and stereo rendering, and a guaranteed large audience so game studios could justify applying their full budgets to AAA VR titles. It would be a huge differentiator at a time when consoles seem to be converging to a very similar place. It could be as big as the Wii was.

With the proliferation of smartphones and projects like Google Glass and Oculus Rift taking off, I really think we'll start to see custom chipsets to improve the performance of augmented and virtual reality systems (battery life, lower latency, and more processing power).

I think the monumental failure of Nintendo's Virtual Boy pretty strongly illustrated that if you can't do this perfectly, you shouldn't do it at all. Within the current constraints (including budget), making a "good enough" product is clearly not feasible. As this article points out, even a few milliseconds too much causes massive problems (worst case: severe nausea – car sickness).

On top of that, it's not even clear that people want this. Full-on Virtual Reality is a bit antisocial and hyper realism isn't the only thing that makes games immersive and/or fun.

Absolutely. But the Virtual Boy was clearly before its time. The hardware just wasn't ready.

I think that's clearly not true. The response from everyone who's tried the Oculus Rift has been that real VR has finally arrived. And the Oculus Rift is one guy's prototype; the resources of a company like Microsoft or Sony could drastically improve it in several dimensions. Specifically, they could source a higher-res, higher frame rate, lighter, lower-latency OLED display, and connect it to rendering hardware with all the latency-reducing features John Carmack just described. These features aren't necessarily expensive from a hardware POV; it's just that nobody's seen the need to implement them yet.

I think VR is fundamentally broken, because you're going to try to react to things in a way that doesn't work. With a head-mounted display, the game can react as you move your head. Great. But then you'll instinctively try to walk towards something and it won't work (or you'll hit the wall). Same with picking things up, etc.

It seems like it's deep in the uncanny valley of experience.
