Nintendo has announced a Professor Layton Vs Phoenix Wright release date of March 28, 2014 in Europe.
The 3DS crossover from Level 5 and Capcom was announced in October 2010 and released in Japan in November 2012, making its chart debut at No.2.
According to the official blurb: "Two of videogaming's quintessential gentlemen join forces to leave no puzzle unsolved in a new adventure - beginning in London before later shifting to the mysterious city of Labyrinthia. The story opens with a young girl named Espella who is being hunted down by witches and seeks Professor Layton's aid, but having been accused of being a witch herself, is also in need of a good lawyer!"
