The motion sickness feeling is not due to the product itself but the mixed sensory perception by the brain when different senses present contradictory signals: e.g. visual movement perceived by the eyes vs lack of movement by the ears. Therefore, a newer product version is unlikely to address this.

Regarding your helicopter question, if you're tied and blind-folded and somebody moves you around, would you be able to fill that? So, in the same way your friend would "see" that he is falling through the glasses, but he would "feel" that he is actually not.

There are several comments on this page that conflict with what you're claiming -- that motion sickness has not been reduced and, for some fundamental physiological reason, can't. First-hand accounts are suggesting otherwise.

I would argue that your brain probably believes what it sees over the sense of touch, at first at least. It would be confused why the body didn't feel anything, but that could be explained by being paralyzed on or some pain-killer.

The new version has positional tracking, so it should reduce the eyes vs. ears problem.
