I think when people are viewing these games as graphical achievements, be it Killzone, or Ryse, or whatever, they're impressed because it is on consoles.
PC is always going to be superior, so when you say it can't compare to what a high-end PC is pumping out, well, yeah, no kidding.
But when you consider it is a 400 dollar console--a launch title to boot, then yeah, I can see the enthusiasm. Look at the stuff we had at launch for 360 and PS3 (PDZ and Resistance); it's nice to see this level of fidelity at launch. To completely dismiss it because PCs have been doing it for years is a bit unfair.
