Dont know if you saw this part too, but there was also a related Order that read:
"The parties shall file a joint status report by no later than May 1, 2018, stating whether the matter should be scheduled for sentencing or whether a deadline should be set for filing another joint status report.”
This could mean different things. The most common explanation is that they want to keep him motivated in case he is needed to testify later.
However, there is at least a possibility that there is more here than the usual. The judge who took his plea recused himself a few days later. The speculation is that he was the same judge who signed off on the FISA warrant(s) that are the subject of the memos, which would raise some issues. Such as, was he the FISA judge who approved the warrant used to spy on Flynn? If so, was this disclosed to Flynn and counsel? Was the approval of that warrant based, at all or in part, on the discredited Steele/GPS Fusion Dossier?
