"So much for the Modern Warfare 2 Wii rumors! In spite of the fact that Call of Duty: World at War has performed rather admirably on Nintendo’s system, Activision has outright confirmed that there are no plans to bring Modern Warfare 2 to the Wii. A representative provided Kotaku with this information, although no reason was given for the company’s decision. I’m sure that this news will leave many Nintendo fans disappointed - myself included. It’s just a shame that the game isn’t in development for the Wii considering how promising some of the previous rumors were."
