I don't know where to start.
First, my heart would almost stop. Then, assuming I live through it, I would post all about it on the messageboard (if there was already a post about it from someone who already saw the same preview while waiting to see the same movie, I would just reply to his/her post). I would just let the whole world know about this highly-anticipated sequel. It's only a matter of time now: Soon Bill Murray is gonna relent on his no-sequel policy (again) an once again reprise his role as Peter Venkman for seven more sequels (j/k, but that would rock though
.)
I'm glad I'm jotting this all down so that I remember what to do when the time finally comes.
