The V finale ep was great! Sure hope "mid-season" is sooner rather than later! It was a mid-season show this season and got moved up to a November start. It all depends on how well other new shows perform and how quickly bad performers get canceled, making room for the pinch hitters.
It may indeed return in November according to this Hollywood Reporter article:
ABC's fall schedule; 'V' may return in November -- The Live Feed | THR
While acknowledging waiting a long time to bring back a heavily serialized show like "V" is always a concern, Patmore-Gibbs said the alien invasion drama could return in November. ABC is considering having "V" take over the "Dancing With the Stars" results show slot on Tuesday nights once the reality show airs its fall finale, which will give "V" a genre-appropriate lead-in from superhero drama "No Ordinary Family." The network also wanted to ensure that the special-effects-filled "V" had enough production time before its premiere date.
