The Disney Channel is so keen on continuing the series that they've already started working on the next one. Most likely, this will be a new television movie, rather than another big-screen adventure, and they're currently writing the script now. Disney Channel Worldwide president Rich Ross says: "Are we going to have all the cast back? Probably not. Will we have some of them? I hope so." The juniors are now seniors? Freshman now sophomores?
To me, this sounds like a new Mickey Mouse Show or something -- a continuing cycle of kids going through high school and singing their hearts out. However, Ross also says: "We have learned that just putting a number next to a title is a very old idea. We have to have a new story." Well, yeah. I'll assume he means a fresh take since it would be pretty interesting if someone just kept remaking the same script over and over. Whatever the case -- HSM is here to stay for the time being.
