NBC has released their schedule of shows they expect back for next season — they include the third season of Heroes, the second season of which was shortened because of the writer’s strike, and the second season of the new series Chuck. The Heroes renewal is no surprise, but Chuck was a little uncertain, since the show fell in the ratings after a strong start.

Despite sagging ratings and what is almost universally considered a “sophmore slump”, NBC’s Heroes TV show lead in the ratings for 2007 among science-fiction/fantasy themed TV shows. Coming in second was Pushing Daisies, followed by the lackluster Bionic Woman and CBS’ vampire show Moonlight, which after a strong start, has fallen way below average in the ratings.
