Hajime Tabata isn't letting shakeups at Square Enix get him down.
After being at the company for over a decade and having a hand in games from Kingdom Hearts Coded to a variety of different Final Fantasy titles (including XV), he announced his resignation from the company just over a month ago. Tabata recently made headlines after his resignation caused to the cancellation of three Final Fantasy XV add-ons, which were supposed to build upon the game's narrative and presumably provide insight into some unanswered questions. And in record time he's founding his own studio.
According to a Facebook post from Tabata himself, he has formed his own company: JP Games, Inc. Tabata notes that he's aiming for a January 2019 launch (which will likely just involve a website and some assets) and asks for "ongoing support." No hints were given as to what the company's first project will entail, but it will presumably fall within Tabata's action/RPG expertise.
