I found an article with Joshua Malina when asked if the show would get renewed he said:
It's a hot topic among the four of us. I'm doing an ABC promo shoot. I take that as hopeful. We're having so much fun together, it would be a shame to end. If I'm going to work, I'm going to laugh.
I personally think this is great news that they are actually shooting a promo for the show. ABC won't have much to work with for next season because of the strike so Big Shots really does have a chance here. Please keep writing, calling and e-mailing and don't forget to sign the petition.
