I came across this an interview with Mark Verheiden on “The Oath” episode.
The whole article is here:
This one jumped out at me:
Ron Moore said last week that things could get worse. Can they get worse than this?
MARK: Please. It’s Battlestar. We haven’t even scraped the surface of “worse.”
It can always get worse. I thought that “33” was as bad as it could get. We had no idea.
Its always good to start a series off with a depression.
It just got worse.
Usually, the Canadian promos are a lot less spoilery than the U.S. ones, but whoa, boy–this one’s not.
There has to be a fake-out there, right? Right?! :eek:
Here’s the thing i see 4.5 as one giant movie so this is really just the first act to me so its dark for sure.(and by dark i mean pitch black covered in innocent blood) but well see them rise up from ashes soon enough 
Blanks. To see if he’d flinch.
And one other thing, K, there’s the jagged tear in the wall of the old man’s quarters that some contributor to the forum keeps beating us over the head with. Very tiresome.
I’m more worried about Tigh, I hope they don’t kill him!! Of course, if he does die, Caprica 6 may go all crazy on everybody, which would be entertaining!! But as more time goes by, I find myself loving Tigh. There’s just something about him!
Like I said before. If Tigh buys it at least he will wake up with Ellen and both his eyes.
Which will severely freak screw Cavil when he see’s him again.
Tigh: Hello Cavil I see you found us.
Cavil: What the Frak are you I took your eye out?
Tigh: I know, I got a new one back.
Cavil: Then you are one of the five.
Tigh: Got it on the first try. I always knew you had it in you.
