"As with any rumor, I would advise readers taking it with a pinch of salt; even one as well corroborated as this one. Having said that, the setting of Greece would chime with other murmurs I had heard from earlier on in the development of Assassinís Creed Origins (previously codenamed Empire). In 2015, there had been suggestions from Ubisoft sources that Greece might appear in the game, but that Egypt would be the focus. Later, these same sources began to report that Greece would instead be saved for the game that would follow Origins."
"The next Assassinís Creed is currently scheduled for release in fall 2019. Our sources indicate that the game entered full production around the start of 2017 at Ubisoft, preceding the launch of Origins. Itís said to be in development for Xbox One, PS4 and PC."
