Ok, the explanation of that for the readers out there who are unaware:
When I said '2nd reprint', I mean '2nd Reprint'. When 2nd reprints occur, they're changed up to be 1 advent at a time and changes are made to their exchange shops.

Neverbloom is mentioning the possibility that the 1st reprint gets rerun here. So, the Ixion & Yatagarasu reprint wasn't actually supposed to run for a couple of months if we stuck by DMM's schedule. Clearly, things changed and we got the reprint early in order for the holiday themed stuff to run during their respective holidays.
In turn, that creates a question: what do we get here when we hit points in the schedule where 1st reprints were supposed to occur?
We don't know, but rerunning those 1st reprints are a likely possibility.
