Will the LOTR trilogy blue ray EXTENDED editions also have behind the scenes?

[chrissyasap]

Will they include the behind the scenes that are on the normal extended editions of the three films in the blue ray versions of the extended films as well as all the commentaries that are on the normal extended editions?
To jasonicus: Sweet! Thanks! I'm so looking forward to them!

They should. They will also have additional features.
