Kamen Rider W Forever and Tensou Sentai Goseiger Movie DVD Release

Toei has now officially announced the release date for the two movies. They'll be released in 3 different version, 6 if you count Blu-Ray version for each respective version. The first one is plain old 2D version, where it's just the movie. The only special features in this DVD is the trailers for the movie. The 2nd version is a special collectors edition. This features are just preliminary, so they might change. They hope to include the Making-of, cast talk, a special post card that still hasn't been released anywhere as well as other things. These two versions will be released on the 21st January 2011.
The final version has the 3D version of the movie, this will be released on the 11th February unlike the other two. However, the 3D version is the only one to have both the Kamen Rider W movie and the Tensou Sentai Goseiger one. They'll otherwise have to be purchased separately.

As of now, there's still no DVD covers. Chances are that they'll be somewhat like the posters.
