Fox's Kevin Reilly says, "Some are going to be graduating and moving on." "Creatively, it would be ridiculous if everybody moved to New York, so there's going to be some who are going to graduate and move on. And they'll come back in when we do special episodes."

Also saying, "Ryan Murphy pitched the arc all the way through next season," "What's going to happen this year is the kids will graduate and we're going to go to New York exclusively through the second half of the year, and then he's got some ideas about what we're going to do next year for the final year."

After the 100th episode, Glee will move its focus exclusively to New York City,
Season six of Glee will be its last.

Glee's returns on February 25, at 8pm
