I continue to be confused by something. Why is it assumed Johns was the original champion and ur-creator of SM/WW simply because he wrote the first few SM/WW moments in Justice League? I think it's far more likely the original plan for the couple, including getting them together and the general outline of what their early relationship should be like, was more of a collective decision. Johns merely had the responsibility for executing it.
Johns didn't start his Justice League with any significant hints that he would eventually build to a SM/WW romance yet he ultimately did just that. Johns, more than any other Superman writer, is in a position to write more Clark/Lois. He's alluded to the possibility that his run will focus more on the supporting cast, including the Daily Planet supporting cast. Superman editor, Eddie Berganza, recently promised Clark/Lois fans that, "[Lois] will continue to play a part in Clark's life, especially with what Geoff Johns has planned in SUPERMAN with John Romita Jr." (Source: Ask Eddie). I'd say anyone hoping for more Clark/Lois team ups has seen enough signs to at least hope for more from Johns.
