I think what is concerning execs right now is how to air the last 10 episodes. It makes no sense to waste its current slot on Tuesdays at 9:00pm with such poor performance. Syfy would do best to air reruns in that slot, since they get better ratings than new episodes of SGU (I love saying that!).
There were rumors that repeats of SG-1 were getting better ratings than new episodes once it moved to SyFy. Since they don't specify which episode the ratings are for, and in fact, one show could in theory place in all top ten spots with different episodes, but they only count the highest one, it was difficult to tell for certain. I do vaguely recall weeks when no new or repeat episode from the SyFy era was shown, yet SG-1 was still at the top of the ratings. So things haven't really changed that much, I guess.
I've heard they're burning off the last five Caprica episodes in a marathon (and I think they're out on DVD before they air), but I can't quite picture them doing that with ten episodes. Maybe an episode a day for two weeks as a sort of special event miniseries thing, or doing a special Saturday and Sunday marathon of five episodes each?
SyFy is notorious for trying to bury shows once they've decided to cancel them. In some cases, they retained "first airing rights" but would air things at 2 a.m. so unless you knew to look, you'd never know it was on. They don't want to risk something that's been canceled getting better ratings after the fact, not even so much as a tenth of a point. It's enough to stir up fans even more than they already are. Doesn't matter that the show is dead, sets are torn down, and the cast and crew have moved on to other roles, it gives some false hope for a revival.
I do wonder if they'll delay airing them until they're already on DVD though. I think that would take a massive chunk out of the ratings, but it's probably a moot point since they've not made a good return on their investment with the ratings they've had. They'll probably do what they have to according to the contract, and that's all.
There's a reason I haven't watched anything on SyFy since I stopped watching SGA. I can't find any sci fi on it. And can't bloody well figure out what the hell "Imagine Greater" means.
