What's in store for Season 3 and 4 of the hit TV series "Glee"?

It has been reported last month in various entertainment sites and blogs that the characters of Lea Michele, Chris Colfer and Cory Monteith, stars of the Fox hit series “Glee,” will graduate at the end of season 3 as new characters are set to be introduced.

But according to Deadline, the three stars are not leaving the show even if their characters are no longer in the spotlight.

Brad Falchuk, the co-creator and executive producer of “Glee” announced that Michele, Colfer and Monteith, who play Rachel Berry, Kurt Hummel and Finn Hudson, respectively, will not leave the show after season 3 as they will have recurring roles in the story.

“Here’s the exact thing: They’re seniors. They’re graduating. But that doesn’t mean they’re leaving the show. It was never our intention or plan to let these people go… They are not done with the show after this season,” he said.

On the other hand, Chord Overstreet, who plays Sam Evans has declined to continue his stint on Glee. The actor was offered a deal to return for ten episodes with a possibility to become a regular at midseason, but turned down the offer.

Overstreet mentioned in one of his recent interviews that he is taking a different route, perhaps to further his singing career, and he thinks it’s the best move for his career.

On the other hand, Darren Criss and Harry Shum, Jr., who portray Blaine Anderson and Mike Chang respectively, will be promoted to series regulars in the upcoming season 3.

Meanwhile, four new cast members have been confirmed to join the series and all of them will have their own stories. Plus the winner of The Glee Project will get a seven-episode arc during the season.

Idina Menzel, who plays Rachel’s biological mother, Shelby Corcoran, will be returning, but this time will be a teacher at McKinley in a storyline expected to last for as many as twelve episodes.

And sadly, no more Charice this season.

“Glee” Season 3 is set to premiere on September 20.
