Since there is new Phoenix Wright game coming to the 3DS in September the time is right for some new DLC; at least according to Capcom. The developer released an 11 minute video today which serves as an introduction to the special post game chapter "The Turnabout that Crosses Time".
The new DLC, described as a sequel to the main story, will be available in Japan on June 30th, a mere 21 days after the release of the game in that region. This "special chapter" will be free to download in the eShop until July 20th, after which you will have to pay to purchase.
No word yet as to when the DLC will be available for North America or Europe, but the game is due to be available in the Nintendo eshop in September.
