As I suspected would occur in the last installment of SciFi Weekend, Caprica has been canceled. Remaining episodes are going to be held until the first quarter of 2011, by which time most people will have totally forgotten about the show. SyFy is looking at another Battlestar Galactia spinoff which will take place during the first Cylon War. Trekweb has more information on the proposed show.
Alessandra Torresani has her farewell on Twitter:
Word is out: Caprica has officially been cancelled! I love my lil cylons so much and will continue to kick ass for you guys! Thanks for the love and support! -Love Mama Cylon
No comment yet from show runner Jane Espenson (who once tweeted as CapricaOne).
A couple of other genre shows are doing better. The BBC has announced a 4th season of Merlin and ABC recently picked up No Ordinary Family for an entire season.
