Find out who stays and who goes in the upcoming season 4 of the hit TV series "Glee."

The characters of Lea Michele, Chris Colfer, Cory Monteith, Amber Riley, Naya Rivera, Dianna Agron and Mark Salling will graduate McKinley High so are they returning on season 4?

Here’s Glee co-creator Ryan Murphy had to say about this matter:
