The director, who was fired from Disney after controversial tweets sent ten years ago were resurfaced by far-right commentators, hasn't yet spoken publicly about the news however Warner Bros. has confirmed to multiple US outlets that Gunn is in final negotiations for the movie.
The scuttlebutt is that Gunn's take on 'Suicide Squad 2' will be a completely fresh start from David Ayer's attempt, which itself was seen as an attempt to run with a similar vibe that Gunn created in 'Guardians Of The Galaxy'. According to a report by Variety's Justin Kroll, Gavin O'Connor was the initial choice to helm 'Suicide Squad 2' and the story he had written was almost identical to 'Birds Of Prey', the upcoming movie with Margot Robbie, Mary Elizabeth Winstead and Jurnee Smollett-Bell.
On the Gavin O'Connor front in relation to SS2, hearing the story he had for the sequel ended up almost being identical to the BIRDS OF PREY story and when that film was given the go ahead to go before SQUAD 2, O'Connor grew frustrated and fell off project to do HAS BEEN instead

Kroll's source says that O'Connor became frustrated that 'Birds Of Prey' was given the greenlight before 'Suicide Squad 2', all of which led to his departure and James Gunn stepping into the fold.
As strong a director Gavin O'Connor is, and you just need to look at either 'Warrior' or 'The Accountant' to see that, he wasn't exactly a strong choice to take on something like 'Suicide Squad 2' whereas James Gunn's work and sensibility feels like a perfect fit. The only question now is whether Gunn signs on for it and if he'll be given the creative freedom to do what he wants.
Considering both 'Justice League' and 'Batman V Superman: Dawn Of Justice' were hacked to pieces by the corporate suits, the fear is that 'Suicide Squad 2' and James Gunn's vision could be diluted by studio interference.
No release date has been set as of yet for 'Suicide Squad 2'.
