Speaking to two independent sources, Kotaku UK has learned that Capcom currently has plans for three Ace Attorney games for Switch. The company is planning to release two compilations in the first half of the 2018- 2019 financial year (between April 2018 and October 2018), one a compilation of the first three Ace Attorneygames, the other compiling Ace Attorney games four through six in the series. However, our sources indicate that this is leading up to something.
Capcom has apparently also begun work on a new mainline Ace Attorney game, aiming for a late 2018 simultaneous global release on Switch and mobile. The new game is planned to contain five cases at launch, and features Phoenix Wright returning as the playable protagonist of the story.
