Hot on the heels of Sony announcing that all instruments for the PS3 versions of three upcoming music games (Rock Band 2, Guitar Hero: World Tour and Rock Revolution) will be compatible, Microsoft has announced that all instruments for upcoming Xbox 360 rhythm games will be compatible too.

In a post on the Gamerscoreblog, Microsoft stated “All the instruments from Rock Band 2, Guitar Hero: World Tour, and Rock Revolution will be cross-compatible. In other words, welcome to the party.”

A game notably absent from the list was Lips, a game from developer iNis that features motion-sensitive microphones and appears to be Microsoft’s answer to Sony’s SingStar series.
