I got it for 360. I was watching some Chargers Highlights last night at around 11:45 and it dawned on me that in 15 minutes, Modern Warfare 2 will be out. So I debated for about 30 minutes, and at 12:25 I finally drove to Walmart and picked up the game. I played til 4 am (one MP game where I got wrecked, 5 to 16 KDR) and then I played the Campaign, which is freaking awesome. Having to wake up at 6 am and go to work sucked, especially on 2 hours of sleep, but the game is so fun.
I recommend it to anybody.
