Mighty Strike-Out Slugger
PC's will always reign supreme. It's as simple as that. Sure people will say that they cost much more, but honestly you can buy a decent to high range computer for the same price as a console at launch.
1) A high-end PC will most likely outlive a console generation. I'm certain that people that got high-end PCs during the last generation are still able to play some of the newer games being released for the new console generation.
2) Games themselves are much cheaper on PC, since there's a lot more frequent and deeper discounts. Games even go on discount for pre-orders. For example, I got Dark Souls 2 for $40 as a pre-order while the console version was still at retail for $60 and I believe others pre-ordered Watch_Dogs for cheaper than console too. Then there's things like the Steam Summer Sale in which people can grab relatively older games for fantastic prices (and even games that aren't as old, Murdered: Soul Suspect was at 50% off, for example). The closest that consoles get is used games and reselling.
When you consider this, I think that PC gaming might actually end up being cheaper in the long run.
