Though filming has not begun for the fourth season of Glee, Fox has released a nice promo touting the next season set to debut this fall.

The 30-second spot asks various questions like, “Who stays?” and “Who goes?” It reminds us that even the writers themselves probably aren’t sure what’s going to happen.

When Glee does return it’ll be moving from Tuesdays at 8 to Thursdays at 9. Three season regulars will be added, and Sarah Jessica Parker and Kate Hudson are set to guest star.
