"Avatar" is coming to DVD, but not yet in 3-D.

Twentieth Century Fox announced yesterday that James Cameron's sci-fi epic will be released on Blu-ray and DVD on April 22. The studio noted the release date coincides with the 40th anniversary of Earth Day, The Associated Press reports.

No announcement was made regarding a 3-D DVD release, but a Fox spokesman said one can be expected in the future. The market for 3-D home video is still in the nascent stages, though TVs equipped for 3-D are increasingly being produced.

The DVDs won't include special features. Producer Jon Landau said in a statement that the lack of extras was done to improve picture and sound quality.

The announcement comes while "Avatar," which won three Oscars, remains in the top-10 at the box office. It has earned more than $730 million domestically.
