I don't think this is it, but they do need to stop for awhile. I could see them integrating VR into consoles (instead of an add on), and, as always, some graphic update. Technology is always improving, so I doubt this is where it'll stop. But they're going to need to be patient. 🤷🏿‍♀️
VR is just not attractive for most people in the way you need lots of space and have to cut yourself off completely from the world and might only find out it gives you motion sickness after you already spent the money.
I feel like they'll keep working on that, to try and make it safer or easier to use. I don't know if I'll be around to see it, but people are pretty clever.
The motion sickness issue might be solved, maybe if you are willing to allow it to interfere with your nervous system on a deep level the bit where your body moves while you move in VR but the issue of being cut off from your surroundings will never go away.
