I see the lack of a trailer as a part of their stated effort to keep the season's movies under wraps; any preview would blow the surprise on at least a few of them, after all.
That said, the actual list of movies leaked
months ago, and some light googling shows it still can be found easily. As someone who went to the backer premiere, I can confirm that it's at least 1/14th legit
It's possible that they'll put up a non-spoilery host segment or the show's intro - 1101's or from a episode further into the season depending on how much they want to reveal about the framing narrative.
