The action RPG Immortals: Fenyx Rising was born based on Assassin’s Creed Odyssey and is likely to grow into its series. If you believe leaker Tom Henderson, the potential sequel to Immortals is reportedly in the pre-production phase.
That is all we know so far, and none of it has been officially confirmed. However, Ubisoft has previously expressed satisfaction with the "healthy sales of the game". The concrete result of the sale was never revealed, but Ubisoft was happy with the positive reaction to the game and pointed out that Immortals managed to attract a lot of new players to the Nintendo Switch platform.
A potential sequel, just like the Assassin’s Creed series, could change the place and time of the action. Who knows, maybe instead of Greek mythology we get another one?
