It is most likely the Borg Queen was taken out of the first wave so she could be used to anchor the second set.
I have no doubt there will be more Borg waves. I'm really looking forward to them all!
When I saw the revised wave, I thought they would have kept the Borg Queen. Now she is the only one missing. Hopefully they will officially announce her soon.
So the Borg figures shown last winter at ToyFair were a human male, Seven of Nine (Borgified) and the Borg Queen.
Then we got the revision wave, which dropped the Queen, and added Seven of Nine (Starflett Uni) and a Crewman Borg.
So where does Locutus fit in? Is the single wave 5 figures, or is this being released into two waves, with Picard and the Borg Queen as part or all of the second wave?
BBTS seems to think Wave 1 (the four figures announced last fall) will be followed up.
I'm looking forward to picking up this series of Borg figures in May!
