With scifi shows and Fox, this is always a safe bet, from an interview with Dekker (who plays the young John Connor on "Sarah Connor Chronicles":

He also said the show will become more serialized and more "science fiction" for the rest of the season (Woo Hoo!). Surely that means we'll get nine awesome new episodes then Fox will immediately cancel it and replace it with something that has the word "Dancing" in the title.

Over the years, it's been a pretty safe bet - bet against any scifi show Fox puts on. They must have some staff that likes scifi, and ad sellers who dislike the demographic...
