The minor ones who haven't had much to do yet. (Tina, Mike, Artie, and even Mercedes)

As Brittany is staying, and Santana's age has never really been established, I'd say we'll get her for another year. Plus, Naya Rivera was only made a series regular at the start of this season, so it would make more sense for her to stay than the others, who have been regulars from the beginning.

The same is true for Harry Shum Jr., but while Naya is, at 24, one of the youngest cast members, he's almost 30 and cannot conceivably play a 17 year old for much longer.

Puck, like Brittany, isn't the brightest, which means that he could possibly be kept back a year. But again, Mark Salling already looks far too old to be a high schooler.

Blaine was introduced as being slightly older than Kurt, so he really should have graduated THIS year! I can see him going with Kurt and Rachel to New York.

Out of all the characters whose futures are yet to be determined, I am POSITIVE that Quinn will be graduating next year. She's one of the few who has actually stated her age, and, as she's older than Rachel, who is also leaving, and is depicted as a straight A student, there's no way she's staying.

I think Artie, Mercedes and Tina might also be staying. And I have a feeling Blaine will too, even though it makes no sense. Lauren, I have no idea.

Jesus, that was long! Okay, I'll shut up now.

I forget where I read it but Ryan Murphy said that Quinn and Puck were also seniors

I heard Tina is a Junior and I want Blaine to go to New York with Kurt and Rachel!!!

If Kurt dosen't get into NYADA, maybeee he would wait around for Blaine
