Does anyone know if Led Zeppelin is going to allow their material on the guitar hero-like games?

They have refused in the past to allow their material to be used on the music simulating games such as guitar hero. So yeah, if anyone knows if Zeppelin may be allowing their music on any of the upcoming games, please let me know.

There is "guitar hero 3" and "rock band" coming out soon, and being a zep fan+ a gamer I'd love to play their songs more than what is currently offered. I haven't purchased any of those games yet because I figure it is really expensive to take a shortcut that doesn't get me close enough to where I want to go.

If anyone knows anything of use in relation to my question, I'd appreciate it if you would pass the knowledge on! Thanks.
