With the advancement in technology, I'm sure in 20 years augmented reality will really kick off. I'm sure they will wonder why people used to play with controllers and not a VR headset... I might be watching too much SAO and I don't even watch that anime.
Greed is mainly what's killing VR imo. It's not that profitable to make a VR game compared to a normal game because everyone has a computer nowadays. Also motion sickness and cost of entry, those are factors too.
