Not quite spoilers...
Hopefully one of the remaining twelve Cylon models will be the Imperius Leader... with only one copy. If Arnold ceases to be governator after Nov 7th, then he could take the role!
That would leave four undisclosed models, which presumably have been taken out of service, except for the models in the field.
I still think Boxy should have been a cylon, but they've pretty much forgotten about him. Tigh's wife, Apollo's wife and **'s mother... would be my choice for the remaining cylons.
