Is David Ayer teasing Black Mask for ‘Gotham City Sirens’?

David Ayer is up to something. The ‘Suicide Squad’ director tweeted the below message last night which has fans wondering what he is up to.

Back in December it was confirmed that Ayer’s next DCEU project would not be ‘Suicide Squad 2’. That gig is possibly going to Hollywood anti-hero Mel Gibson. Instead Ayer was confirmed to be working with old pal Margot Robbie on a ‘Gotham City Sirens’ film.

Could this latest tweet tease that the villain (or one of the villains) in the film will be Black Mask?
