Sony: Rock Band, World Tour Instruments Compatible
Hoping that you won't have to fill your living room up with a pile of plastic toys just to enjoy this winter's bumper crop of music titles? If you're a PlayStation 3 owner, you won't have to.
Sony said today on its official PlayStation blog that it has worked closely with the publishers of this year's drum-and-guitar games to ensure that every instrument is cross-compatible with the other two titles.
So, for example, if you buy Activision's Guitar Hero World Tour and its drum set (right), it'll work with MTV's Rock Band 2 and Konami's Rock Revolution.
In addition, Rock Band 2 and Guitar Hero World Tour will work with Sony's first-party Singstar karaoke microphones.
"We’re still working hard to ensure compatibility between the Guitar Hero and Rock Band titles currently on the market, and we hope to have an announcement on that shortly," added Sony's Michael Shorrock.
Activision announced at E3 that the Xbox 360 version of Guitar Hero World Tour would work with Rock Band instruments, so this means that all console owners can now purchase new music games with confidence.
Um, except Wii owners. Hopefully Nintendo has been as diligent as its rivals.
