I'm not saying that PC gaming is dead, in fact, I play a lot of games on my PC and do prefer the PC experience. I'm just saying that the PC experience is converging with the console experience. The prevalence of cross-platform games pretty much means that games will be targeted to the aged hardware of consoles. Sure, PC users, like they do now, can up the resolution and/or change AA and AF, but they're probably not going to get a drastically different gaming experience. I think it's a shame, but the compute power of the PC above and beyond the console of its respective generation will more than likely go to waste.
I'm very excited for the next gen of consoles to be released, not because I'm a huge console fan, but because I recognize that it will likely mean a whole slew of newer and more capable games will be released for PC. That's the reality of the situation.
