I think they originally planned to have just 10 episodes this season, but after Adult Swim bumped it to 16 they broke it into halves. (Or it sounds better to say it's one season of sixteen than to say it's one season of eight followed by another season of eight. Or it'll sell more DVDs. I can't seem to find the quote at the moment)
Whatever the situation, new episodes can't come soon enough.
So I guess the 'big twist' promised in the advertisements was Randal's heel turn. Damn, that was a dick move. He wouldn't have lost a single thing in recommending Rebecca for a job, and would've looked like a class act.
