Regardless of how 1337 some PC players think they are, they're going to get spanked by people playing on a console
I don't see why, from what I can see PC players will still have an advantage:
+Better hardware / higher framerate
+More configuration/tweaking options
+Hardcore players will likely come from the PC community (since that is the platform most serious FPS gamers have been using for the past 15 years)
+Ability to use 3rd party aids (i.e. background apps) like voice comms program of choice, timers etc
+Probably more choice of hardware i.e. headsets, ability to tweak mouse/keyboard configuration etc
Yes, some PC players will get beaten by some console players, but I'd be surprised if the majority of top players didn't use the PC platform.
