New Super Mario Bros. Wii
Development of "New Super Mario Bros. U" started shortly after the release of "New Super Mario Bros. Wii" and spanned three years. The game, initially titled "New Super Mario Bros. Mii", was first revealed at E3 2011 as one of several tech demos demonstrating the capabilities of Wii U. The demo's visual style duplicated "New Super Mario Bros. Wii", but with high-definition graphics, and playable Mii characters alongside Mario and Luigi. Shigeru Miyamoto later announced that the "Mario" demo would be released as a full game for the system, and would be demonstrated in its revised form at E3 2012. There, the new game, "New Super Mario Bros. U", was revealed as a launch game for the upcoming Wii U console.
