@Laoldar, "Since GH4 will be coming out around the same time as Rock Band"
I wouldn't put GH4's end of 2008 and RB Wii's June 22 as "around the same time".
I agree with your GH4 compatibility with GH3 factor which could be important, but has it been confirmed yet that GH3's guitar didn't work with Rock Band ? I ask this since I didn't play and follow GH3 & Rock Band.
If this is true, I find it amazing (and a little bit stupid), since peripheral compatibility is important for wide-spread adoptation.
