Is there really a demand for a single young Superman over what we have now? They tried to make that work for five years with continually diminishing returns. The only one who made that work was Morrison and he doesn’t have any real interest in continuing it.
The new head of DC from Warner Bros. is apparently concerned with the comics matching people’s expectations of the characters from other media. Hence no more Batman comics with full frontal nudity. The marriage, or at least the Lois & Clark relationship is probably safe given it’s been the default for 40 years of media. Jon is probably less safe, but from a marketing point of view he may be more valuable in the DC Zoom line now.
And Bendis has gone out of his way to talk up the Clark/Jon relationship as being central to his plans, as Jon is a goldmine to him story wise and he sees it as a story of fathers and sons per several interviews. Same with the non-traditional family. Like I said earlier in the thread, we are barely into act one, the new status quo for the family has not been established yet. Assumptions that Bendis is just trying to clear the board of Lois and Jon are premature.
I mean, if anything a teenage Jon is right in Bendis’s wheelhouse.
