ROFL. I can't wait until Activision stops milking this game series. Seriously. Call of Duty 4 was a great game, sold well deservingly, then World at War is released and tons of kids bought the game just because it was a sequel that was basically a reskin of the exact same game.
News flash: Leave CoD to Infinity Ward, or just let the series die after Modern Warefare 2.
That's one thing that I actually enjoyed about Halo and Gears, at least they knew when to end a series.
