At today's Nintendo Direct presentation it was announced that Yoshi will star in a brand new game, developed by the same team responsible for Kirby's Epic Yarn. Yarn Yoshi will be set in a world of textiles and is being supervised by Takashi Tezuka, director of previous Nintendo games such as Yoshi's Island and Yoshi's Story. He is also well known for his involvement in the Super Mario games.
Nice to see that Nintendo is giving their iconic green dinosaur a brand new game since he hasn't been the main character in one since Yoshi Story on the Nintendo 64, which came out more than ten years ago in 1998.
Yarn Yoshi is currently in development for Wii U. The official release date is not known at this time.
