The Michael Jackson documentary This Is It will be released on DVD and Blu-ray Disc on January 26.

Sony's This Is It has rung up $71 million in domestic box office since bowing in theaters October 28, and the studio's plans for its home-video release have been the subject of considerable speculation.

Initially, many observers assumed the studio would push out This Is It discs before the lucrative Christmas gift-buying season. Instead, Sony has opted for a post-holidays release in the hope that seasonal gift-card recipients will use their plastic to purchase discs.

Both the DVD and high-def versions of This Is It will include several mini-documentaries and other special features. The Blu-ray Disc also will include two versions each of the Jackson music videos Smooth Criminal and Thriller.

The DVD of This Is It will carry a suggested retail price of $28.96 and the Blu-ray version an SRP of $39.95. A PlayStation Portable disc is also planned, priced at $24.94.
