Is there a little discord over in the 'Glee' camp? Last month Ryan Murphy said that several major 'Glee' cast members would be leaving the show at the end of Season 3. Their characters would graduate McKinley High and be replaced by new characters, just like in a real high school.

Makes sense, right? Well, yes and no. First, some of the actors concerned -- who are still under contract with the series -- expressed surprise at the news, with Chris Colfer saying that he'd found out via Twitter.

Then, last week Amber Riley said that the actors are all fine with the decision, and Lea Michele tweeted that "It's all part of the plan and it's all good."

Now, however, has Murphy's co-creator Brad Falchuk tossed a wrench into the works?

He told a Comic-Con audience that the characters are graduating, but they're not leaving the show: "It was never our plan or our intention to let them go. ... They are not done with the show after this season."

Oh, but he still had bad news for Sam fans: Chord Overstreet is done with the show.

AOL's Rob Shuter stopped by the fourth hour of 'Today' (weekdays, 7AM on NBC) to kick around the news that 'Glee' actor Chord Overstreet will not be returning to the show. According to Shuter, that may be just the beginning of the cast overhaul: 'Glee' creator Ryan Murphy doesn't want his high school suspended in time with kids who never graduate, a la '90210,' and Overstreet's character Sam's departure is a reflection of that.

"He was in the season last year, he was terrific, everybody loved him," said Shuter. Nevertheless, Overstreet is gone, and there has been news that Murphy will push his other stars out when they graduate. "He said that these kids shouldn't be at school for ten years, that he wants them to graduate, he wants new cast, he wants fresh blood," said Shuter.
