Tea leaves say this means the case likely going bye-bye soon.
Or, they're about to kick it back to the judge as an improvidently granted appeal (the DA filed a motion on that a few months ago) and the case is going to start moving forward again for the not-President-or-Georgia-legislator-in-session defendants.
Or they want to send it back to allow the judge to sort out how to proceed more generally now that the case involves a President-elect. (He'll sever Trump off, deciding whether it needs to dismissed as to him or just put in abeyance, and proceed with the rest.)
Or they decided they just don't need oral argument to decide, one way or the other.
Lots of possible directions it can go from here.
