They could all die, that wraps things up rather nicely. Though, I seriously hope they don't.
And I wasn't surprised about the final cylon. I was surprised about (SPOILER)D's death though WTF happened there? If they don't explain this later I'm going to be very confused.
As for the show in general, I feel like the whole thing has gone seriously down hill. It's still good, but compared to what it was, it's really disheartening. The only reason I am still watching it is that I feel like I have so much invested in each character.
Edit: Also, (SPOILER)Anders is Jimi Hendrix, right?
