Lol and it seems I posted my second reply before seeing this one. But I think we're good now haha
But yeah, that seems to be the idea given that DiDio echoed this even before issue 12 came out.
At least you can say you were more or less right on the money about them going back to the two Earth structure. Makes all the more sense given the fact that they don't seem interested in an actual Earth-2 with the Justice Society as it's main heroes anymore. And I doubt this Earth-1985 will have anything to do with the main Earth similar to how Earth-2 wasn't beholden to Earth-1.
I wonder if each line of books will have a Earth-1985 book? ("Superman 1985" and so on) Or if they'll go for like an anthology book or a set of anthology books?
