Eidos Montreal was at one point in time apparently going to make Final Fantasy 15, which has now been confirmed by a former art director.
Jonathan Jacque-Belletête, who used to work at Eidos Montreal, recently spoke with TrueAchievements confirming a longstanding rumour that the Canadian developer was working on Final Fantasy 15.
"Eidos Montreal brought back Deus Ex. I was the art director on that - Deus Ex: Human Revolution," Jacque-Belletête explained to TrueAchievements about his time at the studio. "Then [I was] the executive art director on Mankind Divided. Then we tried to do Final Fantasy XV. Then they decided to bring it back to Japan - which I think was a big mistake, but it's still the truth. Ours was really, really cool."
