Based on a critically acclaimed series of novels written by two authors (one of which is an associate of GRRM), The Expanse looks to be Syfy's most ambitious series to date. The series premiers in December but the first episode will be available to watch on Syfy's website on Monday (11/23).
Syfy has been trying to return to its roots lately with a lot of decent quality shows, and despite cancelling a few lately (Dominion, Defiance, and Haven), this series looks pretty promising. It looks high quality, has some good people attached to it, and the story looks interesting.
I'm looking forward to it. I hope it's successful, because I have a suspicion that the expense of this show led to Syfy giving up on other shows. And even if it isn't, at least I will have the book series to try it.
