Every time someone mentions 'PC gaming dying', I can't help thinking of this picture:
Also, usually I can't help posting it.
OT: I wonder what the PC benefits of Battlefield 3 will be?
Much more players (64 on PC, 24 on consoles), dedicated servers (could be on consoles too, though I don't think there's any reason to think so yet), better graphics (obviously), probably easier and more versatile controls and quick chat options (really, quick chat is great), customizable controls. I don't think they've actually confirmed much of that but it should be pretty obvious.
