As I said before I am very dubious of back to back seasons stuff. There has been rumors of that happening with Discovery, Picard, SNW and S31 without any official confirmation. In case of S31 the series itself hasn’t been announced yet.
I believe it when they officially announce it. Lower Decks was ordered for 2 seasons and they announced it. Kurtzman has said that Prodigy has the same deal. If any of live action shows gets a 2 year deal there is no reason to keep it a secret.
doing this makes sense economically so it will be something they consider. But actors, especially Sir Patrick, may veto it. Anson Mount already complained about being away from his family for too long doing Discovery season 2.
i prefer the writers plan one season at a time.
