Tim Miller departed the project a few weeks ago over creative differences and then within a few days it became clear through media outlets that the John Wick co-director was heavy favourite to replace him. Leitch, who co-directed John Wick alongside Chad Stahelski, worked as stunt coordinators and second unit directors previously.
The reports also states that Fox are looking develop another sequel with Deadpool 3 but will be looking for a separate director for that instalment. While the news is officially confirmed, it definitely feels like a right fit to have Leitch handle it from the standpoint of the action sequences and stunts.
Deadpool 2 is still scheduled for cinematic release on the 12th January 2018.
