Let's face it: the console war comes down to exclusive software. Everything else can be categorized as either trivial or gravy; the top-notch, must-have software that can only be played on one particular platform drives hardware sales. When Metal Gear Solid 4: Guns of the Patriots came out, PlayStation 3 sales spiked for two straight months. When Gears of War 2 came out later in the year, Xbox 360 sales left the other two consoles in the dust. It's just the way of the industry.
