When you like Dexter on facebook you get all the stuff as it's released by Showtime, and this is the very first thing they've released for the upcoming Fall season.

Prepare to be extremely underwhelmed.

If I remember right the full length trailer(s) usually start coming out in early-mid Summer so at least it isn't too far away. If nothing else I figure this thread could at least be used for Season 7 speculation and plot lines especially with the whole Deb thing.
