Rob Liefeld himself supplied the link to this interview on Newsarama, where he discusses matters upcoming in Savage Hawkman, including the #0 issue. Rob is very high on the book:
Issue #0 is by far my favorite anything I've ever done. We went BIG and received approvals all down the line. #0 reveals Carter's past to both him and the reader simultaneously. At the end of #0 Carter will know where he came from and why he is here. He might not know how exactly he got here but we have to leave some pieces to play with in future issues. But yes, many big revelations are made in #0. I'm not sure Hawkman comes out of issue #0 better than he went into it, it puts him in a really difficult spot, but it's key in setting up what comes next, which is the next biggest thing he will experience.
Sounds like a good time to me! You can check out the interview right here at Newsarama.
