So, if they're shifting their development resources to Switch in 2018, I'd say we can expect a new Yokai Watch, new Fantasy Life, and new Layton games around 2019 and 2020. Though, it wouldn't surprise me if we get a new Yokai Watch game as early as fall or winter 2018, since Level 5 puts out a new game like it's freaking crack.
