I recall that. And the more I think about it, the more I believe we will not be getting a builder pack but some kind of display that includes the remaining 4. Wasn’t there even a Modal Nodes convention exclusive years ago with music? I’m down with something like that. While I’m at it, I hope it’s one piece of a modular Cantina playset.
A builder pack would be nice, though, as a less expensive way than carded singles to get figures for customs.
