A wireless microphone set for the will be offered in stores in time for Christmas, have revealed, confirming that the mics will cost 49.99 USD.

These microphones are presumably an evolution of Lips' sparkly affairs, and we're told they will be compatible with all big games - including The Beatles: Rock Band.

Updates to games (including The Beatles) will be offered via Live, adding mic compatibility, and a release in the autumn is scheduled.

We're expecting word on a new Lips title (or similar) from Microsoft soon. No word on where else this mics will be released yet.
