It wasn't so much exclusive to Japan as much as it was simply unannounced  for North America, but Capcom has confirmed that Turnabout Return, the DLC case and costume pack will be coming to the west.

This is the first time Phoenix Wright will feature 3D polygonal models, so it's the first time costume packs will be an option. Costume changes are difficult for 2D sprites.

Capcom has no release date or price for the DLC, but Dual Destinies will release this fall. For more on Phoenix Wright: Ace Attorney – Dual Destinies, a game whose title has both a colon and a hyphen in it, you can check out the latest trailer.
