Two weeks ago, Harmonix created a software patch for the Sony PLAYSTATION 3 version of Rock Band that allowed for guitar compatibility and support for third party peripherals, including enabling use of Activision"s Guitar Hero III controller with Rock Band. The compatibility patch was submitted, approved and had been scheduled for release by Sony on Tuesday, December 4. Unfortunately, Activision objected to the compatibility patch"s release. The patch remains with Sony, but we have been told that it will unfortunately not be released due to Activision"s continued objection.
