I think GH3 is sort of irellevent, it's coming out for PS2 so surely anyone who likes it has no real reason to buy a new console to play it? :/.
As for Rock Band, it is coming to the Wii in 2008 (CEO of Harmonixer said so / IGN podcast). The time exclusive will obviously help Ps3 / 360, but are people really going to spend $600 to play virtual instruments, when you could buy a real drum kit, guitar, bass and microphone for less? :/.
