As predicted (in post #88), the government has a added 30 days (from 31 Aug - so really about a week from the order date) to complete presentation of its first 50 submissions - with 50 more to be filed each month thereafter.

No punishment for U.S. delay on detainees
Friday, September 19th, 2008 7:15 pm Lyle Denniston
.....
The federal judge overseeing some 200 detainees’ cases on Friday gave the government added time to supply its reasons for holding the prisoners and refused to impose any punishment for delays up to now, but warned that his patience may be growing thin. ...
..... The first 50 such returns are now due by Sept. 30, a month later, and 50 more will be due each month until all have been filed. ...

The opinion explaining the order is here.

The order adds this interesting option for the government - transfer or release of detainees:

(order, p.2)
The Court further ORDERS that, pending further order of the Court, the government need not file factual returns or motions to amend factual returns at this time for petitioners approved for transfer or release from the United States Naval Base at Guantanamo Bay, Cuba.
The opinion makes it clear that the schedule is now a mandate:

(opinion, pp.5-6)
As it is disappointed in the government’s failure to meet the schedule the Court adopted based in part on the government’s assurances, the Court grants the government’s motion reluctantly. ... But the Court admonishes the government that, in allowing it an additional thirty days to file each set of factual returns in these cases, the Court is not merely setting a “goal” for which the government is to “strive,” ... Rather, the Court is ordering the government to produce at least fifty factual returns by month’s end, followed by at least fifty more each month thereafter until production is complete. Nor is the government’s “doubt that Petitioners’ counsel can respond, and the Court can adjudicate, cases at that pace,” Gov’t Reply 4, a basis on which the government can rely to disobey an order of this Court.

While the Court is not unsympathetic to the government’s current workload and that, since Boumediene was decided a little over three months ago, government “[a]ttorneys and others from multiple agencies have worked long and hard, nights and weekends,” see Gov’t Mot. 10-11, 10 n.3, the government has detained many of these petitioners for more than six years, and the time has come to provide them with the opportunity to fully test the legality of such detention in a prompt, meaningful manner. .....
.....
Review of the public and ex parte declarations assures the Court that the government is now on notice of the time needed “to accomplish the development and finalization of amended and original factual returns in the pending habeas cases,” Gov’t Reply 2. Going forward under the revised schedule resulting from the Court’s granting of its motion, consequently, the government cannot claim as a basis for failing to meet deadlines imposed by this Court that it “simply did not appreciate the full extent of the challenges posed,” Gov’t Mot. 3. Except for good cause shown, therefore, the Court will not tolerate any further delay. ....
Meanwhile, in Judge Leon's court, the first habeas evidentiary hearing is scheduled to begin in 2 weeks. The government has not yet convinced him to extend his timetable.

(same SCOTUSblog above)
The Justice Department has made a similar request for more time to file returns in the two dozen cases being handled by a different District judge, Judge Richard J. Leon. That judge had several times told Justice Department lawyers that, if the process was slowed down, he would summon government officials to his courtroom to explain in person.
Judge Leon has yet to rule on the sufficiency of the evidence already submitted - that is, whether it can be unsworn or whether a jurat will be required.
