I think they are going to use twists from seasons past for BB17(maybe a new one or two along the way)
I think Week 1 they'll do the "Battle of the Block" crap, then eventually have the MVP twist(a season without production involved wouldn't be satisfying enough for them)
I expect America's Player to happen 1 week.
Perhaps the duo twist occurs with random pairs.
Maybe there is a week where there is no PoV competition
It sounds like an awful idea to use a twist every week, but they are just so desperate for ratings this season
EDIT: Just remembered they confirmed someone gets evicted during the premiere episodes, so that is twist #1
