Regardless all this, I still think it is possible that it WON'T be addressed. DC has gone to *great* pains to act like the Silver/Bronze age never happened for Superman. Further, Johns had a very clear opportunity to address this back in Infinite Crisis. But nothing!
It is easy to call Geoff Johns on a seeming antipathy to the Superman of the Pre-1986 era, I confess to being not being won over by his work of the character regardless of that argument, and yet... is it strictly true that he has an antipathy? I would say to you no. Consider that he took the opportunity of Infinite Crisis to reformat the backstory of the character to restore Kal-el/Superboy and his Legion career, it was he who reset Clark Kent back to being the bumbling mild-mannered news reporter. It was he who restored the Daily Planet dynamic to more resemble the classic Pre-Crisis era with Steve Lombard reintroduced as sports jock and Prankster. In fact it is fair to say that the Clark kent and Superman we have today is based on his work in that 2006 revamp, and if you read Action Comics, why just last week you still see strong traces of the Johns treatment and its harking back to the old supposedly jettisoned elements of the Pre-Crisis.
I understand the fondness for the Pre-Crisis era of Superman all too well, in some ways that's my default Superman, but as I've pointed out before even if the Crisis had never happened Superman today would never be the same book, or setting, that we were reading in the late seventies and early eighties.
It would have evolved. Changed, both the emphasis of the series and the characters... because look back on the immense changes in the industry in the late eighties and through the 1990s and it is almost inconceivable that the character and his setting could have carried on exactly as was - an unchanging landscape frozen in another time.
I wish that Mr Oz would have been revealed as the E1 PC Superman, trying to bring back intact his PC DCU!
According to DC, this new reboot Superman is still the PC version now in the new continuity time line, correct?
