At last year's Level-5 Vision Event, Level-5 (Professor Layton, Inazuma Eleven) debuted a trailer for a game called Yokai Watch, with plans to create yet another multimedia franchise. At the time it wasn't clear where Yokai Watch would end up, but according to CoroCoro magazine it's set to haunt Nintendo 3DS.
If you missed the trailer when it originally premiered:
Yokai Watch follows a boy who wears a watch that allows him to see spirits and interact with them. There's currently no release date, but we'll keep you posted on additional info.
