The idea that it's refresh rate or resolution that's keeping VR from becoming mainstream seems ridiculous when even a relatively friendly platform like PSVR ships with this bundle of cables: https://upload.wikimedia.org/wikipedia/commons/thumb/3/3d/So...
Occulus seems to realize this but their software side still needs work.
A 480p game on the Wii is still a playable game. An art style that leans into the low resolution will also look fine. While it might not have looked as good as a PS3 it's still playable.
A VR headset with imprecise orientation sensors and a slow refresh rate will make you sick. Your visual input won't match what your proprioception says about your body's positioning. Even if you manage not to get sick such a system isn't usable for non-trivial durations. A low end VR system is not worth any amount of money because it's not practically usable.
Nintendo is the only major player in the handheld category: of course they're a "leader". The success of the Switch supports my prior point: it's a warmed-over Nvidia Shield that has very mediocre hardware (Tegra X1 - Maxwell arch), but has amazing first-party games on it. BoTW is one of the best games I have played.
Yes, cables are also something that lowers immersion.
1080p: I disagree, that can either be good or bad depending on the content. E.g. original iPhone was only 320x480, but Apple made it feel good.
Yes, you can see the pixels. But it’s easy enough to ignore that if the content is compelling.
