I just brought back my PS3 copy of Black Ops the other day. Call of Duty just keeps disappointing me more and more with each new game. The only reason I would buy Modern Warfare 3 at this point is for the story line. As for the map pack I would never spend $10-$15 on a couple maps. Battlefield 3 is going to be the killer of CoD, they even admitted that BF3's engine is more advanced. Especially since Activision has used the same engine since 2005
