The Western release date for the HD remaster of the Ace Attorney Trilogy has been revealed as April 9th by Capcom. The game will be digital only in the West, and will release with English and Japanese language support, with French and German to be added in a post-launch update. April 9th will also be the first time the game will release on Steam, and it's probably the delay in this version of the game that is causing a slight delay in the game's Western release. PS4 and Steam versions of the game come with a pre-order bonus wallpaper.
