I doubt it would be possible in the next 7 years.

The technology depicted in SAO is much much more than simply VR - the Nerve Gear effectively filters out electro-chemical signals being sent from your body (along the spinal cord) and spoofs/simulates the entire gamut of physical sensations based on information from the game client.

Add to that the 'Pain-Obsorber' which is capable of filtering out to varying pain from a given combination of sensations (I say combination because players clearly felt 'something' when they were hit)..

All of this would require humanity to not only have a vastly superior grasp on the central nervous system but also get to the point where said knowledge has already gone through the medical applications to the point where someone would even have access to it in order to apply it to an entertainment application.

I dont doubt that technological advances will continue and that this or something similar could, in theory, happen within our lifetime.. but not by 2022.
