On May 30, 2009 it was announced that two new sequels would be released for the Wii: "Wii Fit Plus" (a sequel to "Wii Fit") and a new Mario game tentatively called "New Super Mario Bros. Wii" (which it was unknown what the name of the game would be at the time), a sequel to "New Super Mario Bros". "New Super Mario Bros. Wii" was later officially announced at the 2009 E3 convention and GamesCom in Cologne, Germany. To highlight the uniqueness of the game, Nintendo chose the color of the case to be red instead of the traditional white.
