I don't think he means that the game will have a cover system, even though the article seems to assume that. I think it probably means that you will run around with the left analog stick, control the camera with the right, pull the left trigger to aim, and pull the right trigger while aiming to shoot. While aiming/shooting, you will probably move considerably slower. And that sounds like a great control scheme, though it reminds me a little more of MGS4's controls than Gears of Wars. I doubt RE4 will let you run and shoot, but force you to go into aiming mode to shoot. That way, it still retains a lot of the tension of being "vulnerable" while aiming and shooting, but not limit you to being a sitting duck.
But I really hope that they include the ability to change which shoulder you are aiming over. Pissed me off in Gears of War that I was always looking over the right shoulder.
