The Amazon leak was incorrect, the game's actually releasing in March not April, as confirmed in this video that showed off the game's opening. Even though this Spring is actually the time to expect Joker and a Persona 5 stage to arrive as DLC in Ultimate, we can still praise at some point in this year that a Yoshi's Crafted World stage will arrive as DLC, they should use something from atleast one of Yoshi's most recent adventures in Ultimate in a way.
