Fox is going all out to promote its move of Glee to Thursday nights this fall. Yes, already.

The network has come out with a teaser for Glee Season 4, using footage from concluding Season 3 episodes and asking questions such as: Which students will go? Which will stay? Where will Will and Emma get married? Will Sue ever give birth?

Watch the first official promo now and remember: Glee airs Thursdays at 9/8c when it returns in September.
