I made this very rough drawings about what i think might change on the ferrari sidepods if indeed they are changing anything...
this first drawing is how the ferrari sidepods look now:
if you look at the lower leading edge of the sidepods you will see that they are like walls in front of the airflow which might be a reason for what is said about the flow not being able to efficiently go to the back of the car....but i think that this is what they had in mind when they were shaping that area...they wanted to extract some downforce from that front part of the floor...i hope you can see what i mean:
and this is what i think they might change...the might remove that 'wall' obstructing the air flow to the rear:
