From imdb.com:
When it is released on August 19, Disneys Hannah Montana and Miley Cyrus: Best of Both Worlds Concert Tour will become the first high-definition Blu-ray release that can be viewed in 3-D, Disney announced Thursday. The company said that viewers will be able to watch in either 2-D or 3-D modes, but it offered few specifics. Presumably special glasses will be required, but the company did not indicate whether they will be included in the Blu-ray package. A conventional DVD package is scheduled to be released on Tuesday. Disney also said that the Blu-ray disk will include a documentary, The Ultimate Personal Tour, featuring Cyrus and The Jonas Brothers, but it was not clear whether the documentary and other extras on the disk will also be viewable in 3-D.
