Udon Entertainment and Capcom will be releasing the artbook for the fifth main series Ace Attorney title, called The Art of Phoenix Wright: Ace Attorney - Dual Destinies, on June 9th:

Dual Destinies

The artbook will sell for $31.20 on Amazon (the official price being $44.99) and includes character designs, pin-ups, storyboards, character profiles and more.

As an avid artbook collector I'm incredibly excited for this one, as the previous Ace Attorney artbooks have all been excellent quality and featured great content.
