Actually, isn't it more than past time for gaming to evolve again? In the past it has been accomplished by designing exclusive titles for the PC due to the superior hardware after the consoles have been on the market for a while.
So get busy devs its time to start making games that will make the current consoles throw up a lung. For the record if the games is actually very good people go out and buy the hardware they need to play it. Crysis was good but it wasn't one of those must play games. How do you think PC gaming started becoming popular in the first place. It was because of companies like ID who created great games that people HAD to play so they bought the hardware to buy it. I bought a $1400 PC just to play Warcraft 2 in 1996. Fortunately an equivalent computer today to play today's games cost half that. Its a great time to be a PC gamer. Time for some devs to open their eyes and see that.
