Sonys Michael Shorrock gab folgendes im Rahmen des PlayStation Blogs bekannt:
For the most part, this means that the titles with musical peripherals will work with the other’s software. A few specific examples include: Guitar Hero: World Tour’s guitars and drums will work with Rock Band 2 and Konami’s Rock Revolution software.
And yes, you guessed it, Rock Band 2’s guitar and drum set will work with Guitar Hero: World Tour and with Rock Revolution.
Conversely, Rock Revolution’s drum set will work with both Guitar Hero: World Tour and Rock Band 2.
Im Gegegensatz zu den Vorgängern wird man Guitar Hero: World Tour oder auch Rock Band 2 mit jewiligen Instrumenten des Konkurrenzprodukts spielen können.
