No exact release date other than this year. You can pre-order it from Amazon for $69 now at least. According to Amazon it’s a 7 disc set.

The only potentially negative news here is that the films will be presented in their theatrical versions instead of the more popular (and more faithful) extended versions.

Figures, so will you wait for the extended version or get this version? I have never seen the extended version myself. Am I missing out?
