Mario & Luigi: Bowser's Inside Story + Bowser Jr.'s Journey (known as Mario & Luigi RPG3 DX in Japan) is an upcoming game for the Nintendo 3DS, set to be released in Japan on December 27, 2018, in the Americas on January 11, 2019, in Europe on January 25, 2019, and in Australia on January 26, 2019. It was announced in a Nintendo Direct on March 8, 2018. The game is an enhanced remake of the 2009 Nintendo DS game Mario & Luigi: Bowser's Inside Story. The remake also features another story where Bowser Jr. takes action on an adventure, similar to Minion Quest: The Search for Bowser, with two important differences shown so far: a slot for an additional second-in-command who will have its own actions just like Bowser Jr. as well as formations for the troops.
