This spoiler is 90% sure true..

Sam Evans WILL NOT STAY WITH New Directions. Sam is integrated with Vocal Adrenaline just before National ( to become their new leader with Sunshine a.k.a Charice ) following disappointments in love with Santana and Quinn.

It will also seek revenge Finn. Expected a bit because Chord is not the only player who has been renewed for season 3 - not only should appear as guest star.

This is rumored to happen in episode 2x19 "Rumors".
