This is true but I think this is mostly irrelevant to the topic at hand. If VR was as popular as PS4 then we'd have said "VR took off". It doesn't need to be as popular as smartphones to be called successful but it's arguably not successful yet by many definitions. It certainly hasn't "taken off"

Most gaming accessories never took off. The racing wheel has been available for decades now and never "took off" and yet it never went away either. Racing wheels have a market and will continue to forever.

I predict VR will be slightly larger than the racing wheel market but they will not become super common in the next decade because they require a large amount of space. This doesn't matter at all because even today VR games and hardware are great fun to use.
