In addition to Mario Odyssey, (can't speak for Pokemon personally) Splatoon 2, Xenoblade 2, Mario + Rabbids Kingdom Battle, Hyrule Warriors Age of Calamity, Yoshi's Crafted World, and Luigi's Mansion 3 are all exclusives worth getting.
Looking forwards, other upcoming ones that look promising include Monster Hunter Rise and No More Heroes 3.
Bet with Liquidlaser: I say PS5 and Xbox Series will sell more than 56 million combined by the end of 2023. (And over 130 million lifetime)
