At first, I said I was going to buy both games.
Then, after a while, as MW3 was being revealed more and more, it is completely bad IMO. Seems like MW2 with almost the same graphics and BO has better graphics than it. CoD is dying, they needa get new ideas.
So now, I'm not going to spare another 60$ for a game that is so so similar to the one I have already. It's like buying a Sports game year by year. You just bought NBA 2k11 and you buy 2k12, completely pointless except with little "tweaks & features" here and there.
