Disney's home video division said Wednesday that it will include 3-D glasses with each Blu-ray disk of Hannah Montana and Miley Cyrus: Best of Both Worlds Concert Tour, but it gave few details about the first 3-D release in the high-definition format. Although it said that four pairs of glasses would be included in the package, it did not indicate what sort of glasses these would be. (Some writers have suggested that they would resemble the primitive red/green glasses of the '50s that many folks complained gave them headaches.) Neither was there any indication whether the glasses would add to the wholesale price of the disks or how much it would cost to buy additional pairs.
