No. Wii rock band instruments can only work on the wii
No
when rock band 2 and guitar hero 4 come out, anyone who has rock band for any system EXCEPT wii will be able to use their rock band stuff for guitar hero, but u can't use guitarhero controllers for rock band
no
the rock band controllers work for guitar hero world tour only
No, the controllers (except the mic) are not cross-system compatible.
Yes it is.
No, you can't use controllers between different consoles, but only with the same console. So you can use Guitar Hero PS2 controllers with Rock Band PS2, but not Wii.
yes they do
Yeah. :):):):):):) i am goofy but that's me --Emmy
Yeah you can use the GH I-III controllers as guitar and bass controllers in rock band. Although you can not use the Guitar Hero 1-3 guitar controllers on the PS3 console. You will need to buy the Rock Band guitar controller.
MTV Games has released on their website that Guitar Hero Controllers will work with Rock Band 2. However, this information was for the Wii game only, and it has been confirmed that the drums will NOT work with RB2 for PS3.
