If you believed the rumors, congratulations!
Harmonix has confirmed via its Rock Band 'zine that a Queen track pack -- ten damned songs! -- will be coming to Rock Band in the fourth week of October. You probably want to know what songs they are, and we're happy to tell you:
Another One Bites The Dust, Crazy Little Thing Called Love, One Vision, Fat Bottomed Girls, I Want It All, I Want to Break Free, Killer Queen, Somebody to Love, Tie Your Mother Down, Under Pressure
So basically, all of the awesome ones you probably wanted. No word on pricing, but you can do the math based on previous releases and you'd probably get pretty close. Two weeks is plenty of time to enroll in some singing classes, or at the very least, start warming up those vocal folds.
