Nightwing left at the end as well, so I could see them soft-rebooting with a bunch of the newer guys as the Genuine main characters. End of S2 mentioned Mars needing help after the Reach invasion, so that would be a fine way of putting Miss M (and Superboy by unfortunate extension) on the backburner.
