Hell no, I won't touch it with a stick, lol.
MW2 is the first game in the COD series I hate to love. I've got pretty high hopes for Black ops, I don't think I'll feel the need to play MW2 again, unless perhaps a friend who doesn't have BO yet wants to play it or something like that.
Unless ofcourse BO turns out to be worse than MW2 as far as noobness (things like tubes, G18, commando, etc) and bad connections goes.
