Queen: Rock Band?

It seems the success of The Beatles: Rock Band has brought on the interest of a number of other high profile music acts including U2 and Queen. Queen guitarist Brian May has stated that his guys are interested in doing something of the sorts and that it may be happening in the near future.

We recently announced that Queen would be contributing a 10 pack of songs to the Rock Band Store and they have contributed songs to the Guitar Hero franchise in the past so the band collaborating with either Activision or Harmonix on a focused Queen game is certainly not out of the question. The real question though is there enough demand for a Queen or U2 focused game to make it a viable project?
