Where the heck was the Borg Queen during everything that went on in that story? With the entire Collective facing conquest by the Cybermen, I'd have thought she'd have been more closely involved.
My working theory around issue #6 was that there was no Borg Queen at this point in Borg history and that the Doctor would unintentionally create the Borg Queen when he rebooted the Borg to save them from the Cybermen and then, for timey-wimey reasons there would always have been a Borg Queen. Of course, it didn't happen that way. Nothing that interesting happened in Assimilation2
I agree with The Wormhole
. It would be a continuity problem for the crew to meet the Borg Queen several years before they actually do in First Contact
. (Ironically, though, the characterizations, particularly Picard, are closer to the First Contact
characterizations than the fifth season characterizations, so in retrospect maybe IDW should have set this after First Contact
