A lot of the techniques and future tech listed here would certainly be nice and is something everything wants; but I really don’t think all of this will be available (for a consumer price) in a year or two already. Some of it, definitely.
Full body tracking for example, I don’t think we’ll see that (especially in suit form) any time soon, for a reasonable price. Not to mention with nice software support.
It’s nice to dream but me I tend to focus on what has proven to be achievable, first. Even oculus does this. Their varifocal display for example is a really cool concept but they were clear that it wasn’t gonna happen any time soon.
