This is just a matter of time and probablt needs few generations of more gamers..

Athletic sports is considered more sexier right now, but after physics and graphics get better and movement gets more variety, they are going to be way easier to market.
And one thing that "real" sports are bringing to the table is athletics, but eSports could fuse that in by brining augmented reality in games too, in big halls, where you could modify the room to respond suits, the results could be state of the art movie-like effects.
