A few days ago, the internet was up in a tizzy about a mysterious trailer released by Bad Robot, the production company founded by Lost and Fringe creator/Star Trek director J.J. Abrams. Now, it looks like we may have an answer to what it's for, or at least a pretty solid clue. According to Brendon Connelly of Bleeding Cool News, the trailer teases Abrams's upcoming novel S., which we've actually known about for some time. Just how did he come to this conclusion?:

Looking back over coverage of these projects, I found a promotional postcard, snapped and uploaded by The Huffington Post. It featured text in a very particular font. The exact same font as appears at the end of the trailer. So now I’m 100% convinced. It’s a trailer for S., a novel by Doug Dorst, devised by JJ Abrams.

The use of the same font could be a big indicator, but it could also be a coincidence. Still, if you've ever watched this guy's TV shows, he doesn't seem to believe in coincidences, so Connelly's assertion may prove true after all.

You be the judge. Here's the trailer:

And here's the aforementioned post card (courtesy Mulholland Books):

The fonts are indeed the same. I guess we'll have to wait until more videos are released to know for sure.

In the meantime, here's what we know about S., again courtesy of the publisher:

At the core of this multilayered literary puzzle of love and adventure is a book of mysterious provenance. In the margins, another tale unfolds—through the hand-scribbled notes, questions, and confrontations of two readers. Between the pages, online, and in the real world, you’ll find evidence of their interaction, ephemera that bring this tale vividly to life.
