Yeah, though it would be hard for me to get excited about Queen. I doubt they'll pick any Queen songs that aren't available in pro guitar in RB (the two I could think of are Crazy Little Thing Called Love and Fat Bottomed Girls. Don't really care about the former, but I'd get excited about the latter, as I think it's the great omission in RB).
I'd probably buy the Queen pack if it looked something like this.
-Fat Bottomed Girls (don't really like the song, but it will most likely be included)
-Crazy Little Thing Called Love
-Tie Your Mother Down
Or they could do a Queen deep cuts pack, but yeah, that's not happening
