I don't watch the show, but from what I understand from reading the entertainment section in the paper, the show is quite popular. So I can see that a spinoff is quite plausible. I'm also sure that the complete series will go into reruns starting within the year. If there is no spinoff then I wouldn't be surprised if the show will be continued again at a later date (possibly within 2 years). Remember folks, you read it here first.
