I know the rock band insturments work on the 360 version but what about the PS3 version

or the wii version?  >_>

*crickets chirp*

<_<

I would assume it goes the the same for both systems, I can't see why not.

I read, I think it was on Kotaku, that all RB instruments would be compatible with GH and vice versa. If I can dig up the article, I'll post it.

I know for sure it works on the 360 for sure

After listening to roughly 12 hours of E3 podcasts from various sources, they all seem to agree that both Rock Band 2 and GH: World Tour will be playable on each others instruments for all consoles.  This is very exciting news, as I was going to write off GH, and not give it a chance, but knowing that I won't need another set of plastic instruments cluttering my living room in order to play this game has convinced me to shell out the $60 to buy the game.

Thats good to know.... give this a look

This is very good news for both games.  Now the question is does the Ion drum set work as a 5-input with the extra cymbals or is it still a 4?
