Ubisoft will not release a new Assassin's Creed game in 2019, chief executive Yves Guillemot has confirmed.

Assassin's Creed Odyssey is due out this October, less than a year after the release of 2017's Assassin's Creed Origins. But this quick turnaround was only possible because the two games were being worked on simultaneously, Guillemot said. There will therefore be no new entry to the series next year—instead, Ubisoft will concentrate on updating Odyssey "on a regular basis" with "new possibilities for play".
