WB told The Snitch that:

that the information from ComingSoon.net regarding the Harry Potter and the Order of the Phoenix DVD, which can be viewed directly via this link, was not information that came from Warner Home Video and remains unconfirmed. This includes the article’s reported December 11th release date for the DVD, which was most likely attributed to the US and Canada, the cover artwork and the list of features on the various versions of the DVD.

I will post the real release date when WB decides to release it, I think they should just get it over with and tell us. He he.
