I think the delay that happened really fizzled any real momentum that they had. I don't think we've ever got an explanation why the releases halted, I suspect that it has something to do with Joe Kubert's death. That's the only thing I can think of for why releases were suddenly halted for so long.
Aquaman #17: Another great issue, and the art has been terrific since Reis left. His departure hasn't affected the book at all. Arthur seems to be growing his beard again since there was some noticeable stubble. The pace of this book is exceptionally good as well.
