I think that the comparison to Age of Apocalypse is a very good one.  When JMS's initial story arc is over, I expect that the timeline will be restored to what it used to be, for the most part - but with some changes carrying over.  Then again, JMS has hinted that when the moment of truth comes, things may not go as we expect; so I'm not going to bet the farm on this. 

That said, I've noticed a potentially rather interesting detail.  Geoff Johns was in on this; and Geoff Johns and JMS are the guys who are going to be writing the upcoming "Superman: Earth One" and "Batman: Earth One" graphic novels, respectively - graphic novels (and subsequent ongoing series) that are supposed to update the setting and characters to a twenty-first century sensibility.  Sound familiar?  I'm wondering (there's that word again) if we haven't just witnessed the birth of Earth One in Wonder Woman 600.
