I don't know the full story, but they seem to be having some trouble with OCTGN updates. They were working on a whole new version of the Mage Wars module for OCTGN, a version 2.0, and were just going to put the new cards in with the release of that, but real life has started interfering with Sharkbait's ability to work on it and he'll have to quit completely here very soon. As he is the main coder for it, this has seriously hampered development. They were looking for someone to take his place. I don't know if they ever actually succeeded in finding someone though.
