I think they are. I've heard it's supposed gonna air when Degrassi comes back on, but I don't think they even started filming, so I kind of doubt that. Instar Star will probably premiere then instead, since that's been off for a while.
Charity Shea said she'd like to do a season for each year at college for Samantha.
It hasn't been renewed yet though or announced, but it is coming back, they'll probably announce it in the Spring.
