I'm one of the few people here who is remotely interested, and I'm older than all ya'll! Perhaps it's because I grew up in a generation where people always talked about VR being the future of gaming.
One thing to keep in mind is that the technology itself is still in its infancy. Obviously, with the heavy headsets, it's not exactly an experience you can do for hours at a time with all that neck strain. But within a few years, you'll start to see companies promoting lighter headsets.
AMD and nVidia have been making investments in VR. Now, one can argue that they failed with their investments in 3D gaming, and thus, their investment in VR will see no return, but that's because 3D never really had a place in gaming, and was never really hyped to begin with. VR is something that has been talked about for decades, but was also something that needed real timing to make it worthwhile. That timing was an era of better graphics, as well as cheaper gyro technology. Better graphics, of course, was the main thing. You know why? Because in VR, each frame must be able to render at a whopping 90 FPS in order to keep most people from vommiting! This was especially tough, because we ideally want HD, even 2160p resolutions, to render in each eye.
Thanks to mobile technologies, the demand for both went up, and the cost started to decline. Unfortunately, with delays to the 16 and 14 nanometer process in CPU's and GPU's, AMD and nVidia were stuck with 28 nm technology, and it was getting stale. Now, we have the introduction of new technologies, including HBM (and soon, HBM2) and GDDR5X memory, smaller die dhrinks and the introduction of APIs (e.g. DirectX12) that, under the right circumstances, can increase frame rates. With the combination of all these coming out around the same time frame, the formula for making VR on a consumer level was finally made real. And, even outside of VR, gamers are only going to reap the benefits from these technologies, and technology companies will only continue to improve their boards because the presence VR practically demands it.
Now, we are at a point where gaming can continue to evolve with the presence of VR. Yes, it is an expensive investment at first (more so for PC's). And while many are still not on board, there are still many who are, but simply can not afford it. All that said, I think it is far to soon to completely dismiss it as a thing that will never become popular. And if it doesn't... If gaming is never to evolve beyond the controller, keyboard and mouse, then gaming itself is only doomed to die in the coming years. You can only keep it fun for so long.
Anyway. Sorry for my stupid wall of text. I'll go hide in my corner now.
