Well, it looks like Code Geass just took a page out of Marvel. During the Sakura-Con event in the US, Code Geass: Lelouch of the Re;surrection producer Koujirou Taniguchi and Sunrise producer Toshiro Fujiwara made some interesting Code Geass-related reveals. As it turns out, they are making a 10-year plan for the franchise, and Lelouch of the Re;Surrection was just Phase 1.
And like the Marvel Cinematic Universe, the project will not just span movies, but other media as well. This would include manga, anime, and other forms of media.
As for Phase 2, Fujiwara admitted that they’re still not sure what it will be. He said that it may take the form of an anime, or a manga. As of now, the two men are still a bit silent on the details. But hopefully, we can have a satisfying ending, much like the MCU for their Infinity saga.
