Theoretically, the people from each colony need to elect new representatives.. at least everyone except Adama's homeworld, since he's still alive.
However, I have a feeling that, considering how long the democratic process takes, there won't be time to elect new representatives before the end of this thing.
And I saw an Ellen (and hopefully Anders) resurrection coming. Her being a Cylon just wouldn't have made sense if she couldn't resurrect.
Speaking of which... we didn't get to see whether Anders lived or died.
