Electronic Frontier Foundation and Public Knowledge step into the legal game. Microsoft issued an Xbox 360 firmware update that blocked a less-expensive and non-Microsoft-made memory card from working on Xbox consoles.

A court date has not yet been set, but it will be interesting to see if this plays out differently than when Sony cried foul against Playstation.”]
