I think HoI II and CK are the Paradox priority right now followed by EU II in Johan's spare time. There was a time when Johan was very enthusiastic and optimistic about working on Victoria, but with the initial, impolite uproar at release and even after patch 1.02, I think he was heartbroken.
My guess is that Johan will return to Victoria eventually, but not too soon. He will not ignore the wants of players and modders alike. Just look how much he has done because of the AGC-EEP's requests --- more provinces can now be added to the map! I project that Johan will return within a few months to begin working on a new patch, though I wish it were earlier. It has indeed been a long time since the last form of any patch.
