It sounds like the long-awaited comic mini-series by Geoff Johns and Jason Fabok, Batman: Three Jokers, may finally be coming out soon, though an official release date hasn't been confirmed. Recently, Fabok revealed that he knows when the series is coming out, but doesn't plan on sharing any information just yet.
The artist recently posted an image of Batman from Three Jokers mini-series with the comment, "Got a massive batch of pages and the book looks tremendous. Brad 'gets' it. Cant wait to show you more." In the post's comments, an Instagram user asked Fabok if he knew when the first issue of Three Jokers would drop. "Not publicly, but I know when," the artist replied. "We are figuring out plans now. I'm almost done with the first issue."
Most of Batman: Three Jokers remains a mystery, though it will supposedly show a Gotham in which a trio of different Jokers have existed for some time. The story will focus on the characters Batman, Batgirl and Jason Todd.
Batman: Three Jokers will release through the DC Comics imprint, DC Black Label, which features some of DC's more adult-themed comics. Other series featured on DC Black Label include Batman: Damned, Batman: Curse of the White Knight, Wonder Woman: Dead Earth and Harley Quinn and the Birds of Prey.
Batman: Three Jokers #1, by Geoff Johns and Jason Fabok, has yet to receive a release date. However, judging by Fabok's tweet, it's likely readers can expect the first of the three 46-page issues to arrive some time in 2020.
