Meh, I belong to that "the last good COD game was COD4" camp. They've done nothing new since, just slapped new maps on the same engine. Until Activision does something fresh and gives a legitimate reason to make a new game rather than just an overpriced DLC for the previous one, they won't be getting anymore money from me.
I'm waiting to hear how the maps are, because that has a huge effect on how quickly I get bored of the game. MW2 was the last one with good maps imo. The majority of the maps of the last few have all been clusterf***s where you constantly get shot in the ass. So far, people have complaining about how big the new ones are, but that's not a problem to me. I'm not so ADD that I have to be shooting at somebody every 2 seconds like 95% of cod players nowadays seem to be.
Man, their live action trailer was so sad compared to the Modern Warfare 3 live trailer... ugh. Though the game itself looks cool, though I don't get how they've turned the dog into a cyborg that is remote controlled.
