I think that's a premature assumption. After all, this is only a 16-episode first season, and we're 14 episodes in. The way that TV these days is defined by seasonal arcs, with each season telling a distinct story that comes to a climax in the finale, I would assume that any major "shaking up" of the current formula would come at the end of the season. After all, things are clearly coming to a head now, with Rittenhouse and Cahill openly taking over the project and the core cast now operating as a resistance cell from within. That in itself is a pretty major change to the formula, and it's the sort of thing you'd expect in the last three episodes of a season arc. Whatever happens over the remaining two episodes, it'll probably end in a way that changes the status quo significantly and sets up a new phase of the storyline for season 2 to tell.
