This has been a pretty much confirmed rumor for a while. This will be the first multi-singer Rock Band.

The Beatles: Rock Band is the music game experience that allows players to follow the legendary career of The Beatles from Liverpool, to Shea Stadium to Abbey Road. Featuring the ability to play drums, lead guitar, bass guitar or sing three part harmony with up to three microphones, The Beatles: Rock Band will focus on authentically recreating the feeling of performing The Beatles music on stage and in the studio.
