It will soon be 4 years since ARMS so the Mario Kart team's next game should come out this year. Monolith Soft is also due, as by the end of this year it'll be 4 years since Xenoblade 2.
The Odyssey team, the Mario Kart team, the Zelda team, Monolith Soft, Retro Studios ... they're all due for a game. Though Monolith is a bit more understandable and Zelda team is par for the course at this point.
The Animal Crossing team is the real MVPs.
