*promote the mystery. Discuss what your theories are.

Self promoting this video and sending it back into the queue for one more try; last queued Monday, August 19th, 2013 2:40pm PDT - promote requested by original submitter RFlagg.

I'll start the theories:

Alfonso Cuaron's upcoming NBC sci-fi/fantasy series Believe. This seems to be the popular choice.

J. J. Abram's special project concerning Rod Serling's "The Stop Along the Way". Serling's last script before his death which he considered his best work. Of course it hasn't been nearly long enough since Abrams got the rights to it for him to have done much with it yet.

Star Wars. Can't see them making a teaser this far from everything yet, and the only thing people seem to point to is the way "Soon he will know" leaves in reverse order ala Yoda speak. I'm not betting on this option at all.

The Crow. Not sure why people are saying that since near as I can tell Bad Robot isn't involved with the reboot at all.

They're rebooting The Crow???? I think the world has officially come to an end.

I'd say Star Wars. Either that or it feels awfully Man Of Steel-ish. Except that whole water part. OH!! It's a Water World reboot! http://videosift.com/video/After-Hours-4-Movie-Apocalypses-That-Would-Be-Fun

Yep, rebooting The Crow. http://en.wikipedia.org/wiki/The_Crow_(film)#Reboot
They have a director and a star signed, with O'Barr on as a consultant, so we'll have to see. They say they are going back to the books... Meh.

The Water World reboot made me laugh.

In the end, it is a teaser for a book
