Well good luck on this one. This is no way to prove or disapprove. In the time I have been on this site I have seen a large number of people say they are tired of console gaming.
They all say they are digging there old PC/laptops out of the closet and want to know if it will run certian games. So as far as figures are concerned there really isn't way to tell.
I was reading the other day how the consoles are dropping in sales but to what not a clue. Well I hope you find your answer and Good luck to you.
