Alright well I was playin Black Ops on the Wii(yes I'm a noob thnks for askin) and when I was playin with some of my allies, the topic of new maps came up and a few of them said that we were gonna get a map pack In around 4 days... A few lobbies said that too. is it true? Is wii actually gettni maps in a few days???
