It's also possible they have decided to go down the route that Williams and Red Bull did last year and keep the barge board area basic. I don't know why you would... But it's possible.
Everyone was saying RBR and Williams would 100% have more complex barge boards by Melbourne in 17, but we all saw that they chose not to.
If they did make this move, it would be a pretty decent mistake I would guess considering that the 2 cars that had less complex barge boards at season start also had much more complex structures by season's end.
