While I don't think there have been any official announcements about it, word is trickling out that Grant Morrison's "putting the sex back into Wonder Woman" project is going to be Wonder Woman: Earth One. Bleeding Cool poses it as a question, but on the most recent 3 Chicks Review Comics podcast, Greg Rucka confirms it. He also says the gig was originally going to be his.
"I, at one point, was supposed to write Wonder Woman: Earth One," he says. " J.H. [Williams] was going to draw it." Unfortunately, "I was told I was not going to do it. Dan DiDio called me and told me he was giving it to someone else. And I said if you take that away from me I can no longer work for you because I have taken many a job for you, sir, on the promise of doing this and now you’re taking it away and I can no longer accept your promises any more. He had his reasons for doing it; this is not me throwing stones. This is just the way things shook out."
My first response is to wonder why there's not room for both projects, but of course only one of them could be called Earth One. Those volumes have been doing incredibly well and are becoming a successful enough brand that it's now a big deal to write one. It sucks that Rucka was told the gig was his only to have it taken away and given to a more popular writer. That doesn't mean that Morrison and Yanick Paquette's version won't be cool, but it's disappointing that it'll be at the expense of Rucka and Williams getting to tell their story.
