Some of the stuff from the Rebirth series directly references the past series. Other stuff, you need to fudge the details with, as I said. Like, in
Aphrodite IX #0 you see a mechanical Aphrodite being constructed. And on the next page you see the IX mark. But during the construction you don't see this, and there is another Aphrodite seen in a tube later in the series. We know Aphrodite IX is biological, not mechanical. However, the Aphrodite seen later is likely Aphrodite X (she can't be a duplicate Aphrodite IX, because we know from Rebirth that there are no duplicate IX's). And we know Aphrodite X was mechanical. So, what if the same scientists are working on Aphrodite IX and Aphrodite X in the same lab?
That isn't what was intended, but it would make a good retcon if you wanted to consider the earlier series as being in continuity.
So, I would say that series should be considered in continuity, but that the continuity is 'fuzzy'.
Thank you for the welcome back, although unfortunately I don't really think I can make it on to here as often as I did.
