So why release first on Xbox 360? "Microsoft has been a great partner throughout the launch of Rock Band in the last year and their continued support is instrumental in supporting the more advanced features and cross title compatibility we will have in Rock Band 2," a Harmonix representative told IGN. "Of course, our goal is to make Rock Band 2 accessible to all and we look forward to bringing Rock Band 2 to all relevant platforms later this year."
