All the ships that Cube attacked were not necessarily destroyed more so than boarded and their crews assimilated. The Cube didn't have to release a Sphere, because all that wreckage was recycling itself into a new Borg Fleet... Or at least the larger chunks. Maybe they took back booty, and maybe the Borg issued a retreat order when they saw that the Cube had been lost?
That is an idea I hadn't considered and would be very plausible. They boarded the Roosevelt
and began assimilating the ship and crew, but were no where near ready before the Cube moved out of Wolf 359, or for the E-D's arrival.
Then following the incident above Earth they were ordered to return to the DQ. They could have easily developed a transwarp coil and gotten out of UFP space before they were noticed.
Thank you Guy.
