@guesty_01: That point can be turned around. The PC also has platform exclusives and the biggest back catalogue by far, including backward compatibility concerning current-gen console exclusives when the emulators inevitably come out after a few years once the tech allows. How you make decisions concerning spending your own money is up to you, but I personally would not let a handful of games that are only going to be available on one console sway me into parting with 400-500 quid. What happens when I've played them? I'm then left with the same old situation of an inferior piece of hardware playing inferior versions of the rest of the games at a higher price.
It just doesn't make sense to me.
Also to address the strawman argument you set up - I did not say graphical fidelity was the overriding concern, but in this day and age why settle for an inferior product and pay more for it? When you CAN have all the polygons and the framerate and the anti-aliasing and the hi-res texture packs etc for a very reasonable cost compared to the alternative, why settle for less? My favourite game of all time is Dungeon Crawl Stone Soup so I'm hardly a graphics whore, but given the options available, sticking with PC, for me, is a total no-brainer.
@razzdrazz: "Still, I'm super tempted to just save up a bit extra and build a new pc. My computer from 2006 just doesn't cut it anymore, especially in the living room..."
Do it, you absolutely won't regret it, and saving the small amount extra now, and priding yourself on having that little bit more patience than most in order to enable you to wait it out happily, will save you buckets of cash over the generation.
