I'm assuming "video works" = new anime

Also, from the Newtype January issue, there's going to be a new manga series serialized in Shonen Ace.

Starring a NEW main character, Renya, the adventure of “Code Geass” unfolds once more. A new manga script writer, Goro Taniguchi, makes his debut with the newest “Code Geass” project serializing in the monthly magazine, Shonen Ace. A manga series with Taniguchi, the director of the anime, writing the script, and Tomomasa Takuma doing the artwork. “I show much gratitude to both the head editor of Shonen Ace and the manga artist, Mr. Tomomasa Takuma. I’d like to take on this project as a challenge, being an inexperienced manga script writer,” says Goro Taniguchi.

The long-planned project finally comes to materialize. “The new project, ‘Renya of the Dark,’ will be an episode within the ‘Code Geass History.’ There will be stories from two different eras in the same world. The anime featured the ‘Lelouch of the Rebellion’ chapter, and we see this as the ‘Renya of the Dark’ chapter.” This “Code Geass” will be expressed through manga. READ THE REST HERE
