Alfredo Chavez, the gameplay/art producer for Boogie gave an interview recently. He confirmed that the game will ship with a USB headset included.

You start off by creating and customizing your character, known as a "Boog". You use the Wiimote and mic provided to sing and dance your way to fame.

• Large choice of hit songs spanning four decades. Many genres covered, from rock to pop, disco to funk.
• Motion based controls using the Wiimote to dance, shake n move while the Nunchuk can manipulate the upper body and facial expressions.
• Use the editing toy to make music videos, with varying camera angles and effects.
• Mini-games, co-op gameplay, head-to-head battles and karaoke parties.

If you're into party games it could be a winner I guess. This kind of stuff turns me right off though.
