When dose the next season of Total Drama Island come out?

I don't mean when they had to do it all over again scene the alligator ate the money box. cause i haven't seen the early episodes and i don't know much about the people. I have seen the ones were Courtney, Eva, and Gwen's boyfriend got off the show and the first 10 minuets of the episode were Owen won. So I want to see the episodes with new people so I don't get confused and have to ask my little brother whats going on.
