This is the 3DS game
Nintendo has confirmed the release date for Yoshi’s New Island — March 14, 2014. The game is being developed with Takashi Tezuka on staff, who was the creative director of the original game. Yoshi and Baby Mario will return for another adventure, along with the classic flutter jump move eggs, and “some new actions” only on the 3DS.
I’m not completely sold on this yet because I feel like Nintendo hasn’t shown anything particularly spectacular on it, but as a massive Yoshi’s Island fan, I’m eager to see what it can bring to the table.
