Prior to this it was announced that the Sword Art Online series will have a new season, and it is believed that the new season will cover the arc Alicization from its light novel. But there is no official information or announcement that says that this series will review the arc in addition to testimony from the fans only.
But in DVD Sword Art Online: Ordinal Scale is released for the rental version, there is a scene that has not been shown before and be a clue if the following series will review the arc.
The preview is a sort of after credit preview of Marvel movies. In the scene Seijirou Kikuoka looks, the ministry agent who always accompanies and gives Kirito a job along with professor Shigemura Tetsuhiro who became the antagonist character in the movie SAO: Ordinal Scale. Kikuoka takes Shigemura's professor into a room, and then shows a large screen. In the big screen, it looks like a picture of Central Cathedral from arc Alicization.
Unfortunately because in addition to this temptation there is no other information about whether this series will be a new season or a movie. But given the length of this arc, I'm not sure the movie will be enough to review all the stories. The airing date for this arc has not been announced yet, so please be patient again.
