I'm holding off on Call of Duty: Black Ops for now. Wait and see approach. Treyarch is the developer for this game and every time they have had their hands in a Call of Duty game, they have been disappointing. Infinity Ward is the developer that put this series on the map. Their work speaks for itself.
Lets break this down.
Treyarch: Call of Duty 2: Big Red One, Call of Duty 3, Call of Duty: World at War.
Infinity Ward: Call of Duty, Call of Duty 2, Call of Duty 4: Modern Warfare, Call of Duty: Modern Warfare 2.
Iím armed and Iím drinking. You donít want to listen to advice from me, amigo.
