Just heard that the makers of the Guitar Hero games is making Rock Band.
They totally ripped my idea off (me and about anyone who ever played the game )
It will be released on the XboX360 and the PS3. Using two guitars controllers (lead and bass) along with a mic and a "drum set" controller, you and your friends can have a complete rock band.
online play will play heavily into the mix allowing you to play with band members from anywhere.
I've heard some rumors that it will be crazy expensive with all the extra controlling devices, but I am real excited about this one.
