Ubisoft has announced that The Crew 2 will be delayed until "the first half of Ubisoft's next fiscal year" that begins April 1, 2018. The original release date was targeting March 16, 2018. The company indicated that this provides the team more time to "fully express their creative vision".
Speaking with regard to Assassin's Creed Origins, which was also slightly delayed, but with emphasis on The Crew 2 delay, Ubisoft's Christine Burgess-Quemard said, "As expected, this had a very positive impact on the game’s quality and largely participated to its commercial success. Taking a similar approach, we have decided to invest additional development time in three upcoming games."
