According to this Famitsu scan posted by @Lite_Agent, this new game takes place during Japan’s Meiji period (1868 - 1912, a.k.a. Rurouni Kenshin times) and naturally features a new star — it looks like that star is an ancestor of Phoenix Wright. He has a sword, too. Cool sword, new guy.
The full title, according to @CourtRecords_, is Dai Gyakuten Saiban - Naruhodou Ryuunosuke no Bouken, or Grand Turnabout Trial - The Adventures of Naruhodou Ryuunosuke. As mentioned previously, Ace Attorney creator Shu Takumi is once again heading the project, after taking a break from the series with Dual Destinies.
