SiNG, the working title of an interactive dance/karaoke game, was shown by Nintendo during their press conference today.

Developed by FreeStyleGames, who made DJ Hero, and scheduled for a holiday release, SiNG allows an unlimited number of people to participate in singing and dancing activities.

During play, one person will act as the main performer and hold the GamePad to view lyrics and receive cues for moves or claps, allowing them freedom from the TV. Other players use Wii Remotes to interact. The GamePad can also be used to mix audio and creates playlists in certain scenarios. Video of people playing the game showed the main performer using a microphone accessory that was not spoken about during the E3 presentation.

In "Sing" mode, up to two players can perform one of the game's dozens of songs and be evaluated in real time

SiNG is slated for a holiday 2012 release.
