My speculation is not that they are leaving the door open for reissues, but the "sold out" items may have very limited stock that is being held back for potential replacement of fulfilled orders with QC issues or lost packages and so on.So is everything else up for reissue? They've said they won't do that. "Word matter in the crucible" — but I don't know what they're saying ...
Once they feel they no longer need to hold on to them for customer service reasons, they could make that limited stock available via in-person sales at conventions. And they are laying the groundwork for the possible kerfuffle posts of "How come you had 3 Savage Lemurians at the con when you said they were sold out?"
But that's just a guess. They may not want to admit they have any extras so as not to encourage folks begging for a figure...
