I suppose so. I mean, the timeline does have Lex as president around when Jon is born. And in the case of the New 52 --please keep your hopes in check-- but given the fact that 1) the motto is apparently "we're gonna try an fit in everything" and 2) Aquaman's team with his New 52 team when he was young is still here when he was young, the idea seems to be to fit in stuff were they can and how they can. So Clark's first year as Superman --again, please keep your hopes in check-- is like an amalgamation of the New 52 and the actual Golden age.
Hey! I see that smile creeping across your face and the hope welling up behind your eye. Stop that! I will not be held responsible if this isn't the case.
I'll just say that the timeline does have the New 52 armor in it, but it's in 1994 as oppose to when Superman started back in 1962. So, going off Aquaman again, it could be a situation where they just elongate the time and shuffle things a bit. Aquaman joins The Others around the time Clark hangs up being Superboy. He then has normal adventures as Aquaman and even joins the first incarnation of the JLA and then in 1994 (when Clark gets his New 52 armor) he joins the New 52 version of the Justice League. So you see what I mean? It's not *exact*. They aren't scared of splicing events. We know this because Pa Kent is said to die just by himself well after Clark is Superman. But it does try.
So, he could very well started off as Superboy without the power to fly, quit for 8 years, came back at 26 as Superman but still unable to fly, had some amalgamation of early Morrison and the Golden age for a year, then learned to fly the year he meets Batman and form the world's finest, and then formed the silver age JLA.
Or they're just gonna scrap Morrison's stuff in favor of *just* a straight up Golden age start. But chances are the good that they won't have to. The only thing that changes is that he gets his Kryptonian armor not much later and only wears it for a year before Oz Effect.
Like I said, please keep your hopes in check lol
And so it begins.
