During the Nintendo Direct feed today, we got a good look and a target date for the next Yoshi game, Yoshi's Crafted World. The game looks like a combination of a DIY festival and a bunch of Labo kits put together to make a cardboard version of previous Yoshi titles, which gives it a nice look and feel. Kind of like Kirby's Epic Yarn once was. Here's Nintendo's official description for it.
Play as an adorable Yoshi traveling through a world crafted from household items like boxes and paper cups in this new Nintendo Switch platforming adventure. After traveling through a perfectly constructed stage, players can start at the goal and journey back to the start on the "flip side," the backside of the course, to discover secrets.
Right now, Nintendo is aiming to release the game sometime in Spring 2019. If previous patterns hold from Nintendo's schedule, we're predicting you'll see it late April or early May.
