Two days after that (i.e. last night), it turned out that sets are being scheduled for deconstruction. So it is really an existential threat at this point (if they tear down the sets, it'll add a big up-front cost for any party that would like to pick the show up in the future).
That does sound serious. There must be something I don't understand about the SyFy relationship -- I'd think that the company who owns and finances the show would decide when to tear down the sets and that they'd want to do it after shopping the show around. Too bad, I liked the show.
It does sound as if Alcon knew it was coming, tried to shop around in secret before, didn't succeed, and wrote the current announcement to sound like they haven't already given up on the show. I hope I'm wrong about this.
