Update: Also no surprise: in addition to Once Upon a Time, ABC has renewed Castle, Revenge, Grey's Anatomy, Modern Family, The Middle, and Suburgatory too.
The fates of other shows haven't been determined yet though we'll be a little surprised if Happy Endings, Private Practice, and Apt 23 aren't renewed (and more than a little surprised if Body of Proof is). Based on previous years, I'd guess most, if not all of the ABC renewals and cancellations will be out of the way by the end of the day Friday.
Once Upon a Time executive producer and co-creator Adam Horowitz just tweeted the following:
It's official --
#OnceUponATime has been picked up for season 2. Thank you all so much for watching, we're beyond thrilled to continue on!
Another one that wasn't ever in doubt. No word on the episode order yet, but it's surely a full season. Finally an ABC renewal!
