There has been speculation for several years that the studio at one point led the development of the project. In 2018, for example, YouTuber Super Bunnyhop reported on the existence of the project saying that the Montréal studio wanted to make a "space opera RPG" with Final Fantasy elements. He also stated that Eidos Montréal had "some basic art" and "some basic game design".
Deus Ex: Human Revolution was released in 2011, and Mankind Divided was launched in 2016, the same year that Final Fantasy 15 was released. According to Jacque-Belletête, the studio worked on Final Fantasy after these two titles, so most likely, it was just an early conceptual stage.
In early May, Square Enix decided to sell Eidos, Crystal Dynamics, and Square Enix Montréal to Embracer Group. The deal is expected to close between July and September.
