Updated with Misha Collins news! As the Winchester boys work on Supernatural to close the gates of Hell using the demon tablet, they are still unaware that an angel tablet is also out there. And that tablet could send all angels away forever. But what would happen to Cas? Would they be willing to banish Cas to get rid of all the other angels? Jared gave spoilers to Zap2It:
"I absolutely think the boys would sacrifice Castiel to get rid of the angels. I think they are, not one-track minded, but goal-oriented enough to where you've seen them sacrifice themselves or others to try and accomplish a bigger objective ... I feel like they would do it. I could be wrong, but I feel like they would do it."
Do you want to see Cas banished with the other angels? Or do you think they will find a loophole to let him stay?
Update: Misha Collins will be returning as a series regular in Season 9!! (Read the news here.) So I'm thinking they find that loophole...
