Nintendo just announced a Direct for tomorrow night.
The Nintendo Direct will take place tomorrow night at 10 PM (UK Time) and focus on both Switch and 3DS games coming out this year. The Direct will be global and there will also be new details revealed for Mario Tennis Aces. I expect a release date for it. We might get a release date for Hyrule Warriors Definitive Edition as well. Since they mentioned 3DS I also expect details for Sushi Striker to be revealed and hope to see a Yo-kai Watch 3 announcement.
You can watch the Direct here at 10 PM tomorrow.
