Two days ago, on December 11th, 2007, Activision had a class-action lawsuit filed against the company due to “deceptive and unlawful conduct.”

The whole issue stems from the Wii version of Guitar Hero III putting out only mono sound, when advertisements for the game claim it supports Dolby Pro Logic II. Even though Activision released a statement on 12/6 saying that it would replace discs beginning in early 2008, that didn’t stop the main plaintiff of the case, Samuel Livingston of San Diego from filing the suit two days ago.
