Three of Glee's biggest stars, Rachel (Lea Michele), Finn (Cory Montieth), and Kurt (Chris Colfer) will not be return after season 3.
Rachel, Finn, and Kurt are the glee club's seniors, so the rest will stay and who knows who else will join. Quinn, Puck, and Santana are probably going to stay until the end of the season, considering they were nominated for the Junior Prom court. So, they will probably be seniors, too.

Glee Season 3 will premier on Tuesday, September 20 (six days before my bday ;D) at 8pm. Don't miss it. :)
