They aren’t going to cancel mid season, especially since no one likes any of the new ABC shows. Ten days in the Valley is already cancelled. Kevin Probably Saves the World is most likely cancelled. Inhumans is probably cancelled. Scandal is ending after this season. I think they are really hoping that American Idol will do a lot for them, which i think is odd, but who knows.
They will air out the rest of the full Season order as planned, and a cancellation or renewal likely won’t be revealed until May like almost every Season. Unless they decide to formally announce that the series is ending during ABC’s Winter Press Tour date in January.
