In a recent interview with Japanese industry site Jiji, Capcom COO Haruhiro Tsujiro revealed that the company is currently working on new games for Nintendo Switch, including an Ace Attorney title.
Very little details were given other than that Capcom is working on games based on series that are popular inside and outside Japan, including Ace Attorney, and that they plan on releasing the games in fiscal year 2018, which runs until April 2019.
Capcom has yet to confirm whether the Ace Attorney game for Switch will be a brand new entry in the series or a remake of an existing title.
