I have seen a couple of people reference the idea that they are glad they didn't buy too many Rebel Z-95s, since there will be the Scum ones forthcoming. But if the pattern of previous releases holds, (for example, no Alpha cards in the Imperial Aces box) there won't be any way to double up on the fact that Z's are dual faction. Unless they break pattern and include generic Rebel cards in with the Scum package, you might as well consider those two different types of ships.
So if you want to field a massive 8Z Rebel swarm, you still need 8 Rebel Z-packs.
Am I missing something?
