Nobody's mentioned user-made mods yet. Do they have those on the consoles? Games like Counter-Strike, TrackMania, X-Plane, rFactor, et cetera that support user made tracks, planes, changes, or total conversions would never work on a console. Console gamers get the game they paid for and are stuck with it as the developer intended. And they are $20-30 more expensive. No thanks.
Plus, I've personally reviewed 400 PC games in the past almost three years. Yep, sounds dead to me.
