Tom King, the writer for DC's mainline Batman series, has provided an explanation behind the delay of his and artist Clay Mann's Batman/Catwoman spinoff series. Initially set for a January release, the 12 issue maxi-series has now been pushed back indefinitely.In a series of posts on the his Twitter page, King detailed how the delay came to be. "So. We decided to go big," he said. While working on the initial issues of Bat/Cat, [Clay Mann] and I started to realize we might have something good here, a Mister Miracle or a Vision in the world of Batman, an attempt to do what Frank [Miller] did with [The Dark Knight Returns], a defining of the characters.RELATED: Batman/Catwoman Will 'Define and Redefine' the Characters, King Promises

"But to accomplish something that ambitious requires a minimizing of compromises," King continued. "DKR did not have fill-in artists. So Clay offered to do the whole thing, at 22 pages, but he’d of course need time. When the best artist in comics says 'let’s do it right,' you don’t say no."

The Batman writer then concluded his statement. "But all that means that Bat/Cat is pushed back a bit, which is why it’s not in the January solicits. The first scripts are in; Clay’s drawing them now; they look gorgeous; I, hopefully, like you, can’t wait for this one to be out. Thank you all for your patience."
