User blog comment:C.C100/Code Geass Questions!!!!/@comment-853396-20090824162235

A third season is simply fan speculation, since there hasn't any official word about one. The relationship with the Code and Geass has always been very muddled since the story of R2 is very incoherent. I suppose however that if there is a third season, they would be dealing with the origin of Geass and the Sword of Akasha since there was no explanation on where they came from.
