According to John Singh, spokesperson for Lucasfilm Ltd., "Lucasfilm Ltd. has no plans to release any of the Star Wars movies on Blu-ray or HD DVD. Listings on Amazon.com or any other Web site are purely speculative and erroneous."
Amazon.com also has a speculative listing for The Lord of the Rings Trilogy on HD DVD. New Line Cinema hasn't discussed its plans for Lord of the Rings, beyond hinting at CES that the trilogy is in the works. New Line's parent company is Time Warner, also parent company of Warner Brothers. Warner supports both Blu-ray and HD DVD.
Amazon.com declined to comment on how the shopping site generates such information.
