Nintendo announce a new Mario & Luigi RPG for 3DS

Nintendo has announced an all-new entry in the Mario & Luigi RPG game series today, as part of a live 'Nintendo Direct' conference which declared 2013 the 'year of Luigi.'

Nintendo boss Satoru Iwata donned a Luigi hat to talk about new developments for Luigi including Luigi's Mansion 2, his own downloadable platformer for Wii U and the announcement of this new title in the Mario & Luigi RPG series.

Details on the game are scant, but Iwata referred to the game as a Role Playing Game and revealed that much of the game takes place in Luigi's dreams, with players sometimes manipulating Luigi from the waking world to influence his dreams. It was given a vague release window of 'This Summer' - we'll likely see more of the title at E3.
