The CW has taken the suspense out of series renewals this season by picking up all 11 of its current scripted series.
Renewed for next season are freshmen DC’s Legends of Tomorrow and Crazy Ex-Girlfriend as well as The Flash (Season 3), Arrow (Season 5), veterans The Vampire Diaries (Season 8) and Supernatural (Season 12), The Originals (Season 4), iZombie (Season 3), Jane the Virgin (Season 3), The 100 (Season 4) and Reign (Season 4, sans departing co-star Torrance Coombs) .
Some of the renewed shows will be for midseason and/or summer, and not all of them are geeting full-season 22-episode orders. For instance, The 100 has been built for a limited run, and iZombie too is yet to air a full season.
