I really don't know what will happen for the good of the sport Ferrari deserve to be stripped of all points and given a 3 race ban if not longer however I really hope that does not happen as much as I don't toe the F1 needs Ferrari line I do feel that F1 would miss Ferrari and the FIA would not make the mistake of upsetting the fans like that
What is interesting is that the hearing is on a Friday of a race weekend and isn't happening mid week which would imply that the FIA expect it to be a short hearing feeling that they don't need any further evidence from the teams or drivers (as they will be busy in practice sessions) and I think that is very telling when you think about it I looks like this is not to allow further discussion about the guilt of the team.
If the FIA felt that Ferrari had no case to answer they would just release a press statement and say so and call an end to it for the good of the sport
If the FIA feel that Ferrari are guilty then it will be a matter of finding an appropriate penalty.
If you look at lie-gate where the crime was lying to the Stewards which Ferrari appear to have also done then when the WMSC announce the penalty they said the following as part of the statement
Following the hearing a WMSC statement read: "Having regard to the open and honest way in which McLaren team principal, Mr Martin Whitmarsh, addressed the WMSC and the change in culture which he made clear has taken place in his organisation, the WMSC decided to suspend the application of the penalty it deems appropriate.
"That penalty is a suspension of the team from three races of the FIA Formula One World Championship.
"This will only be applied if further facts emerge regarding the case or if, in the next 12 months, there is a further breach by the team of article 151 c of the International Sporting Code."

What will Ferrari have to do if they want to get away as lightly? The FIA have worked hard to show they are been consistent with penalties even if that that appeared to be harsh (Scumi and the SC) or soft (Lewis and the SC)
The WMSC will be aware that people and the media are drawing parallels and I think their hands are been tied.
How far will Ferrari have to go to show they have changed? sack SD and perhaps even RS? re-write Massa's contract removing the so called Baracello clause? Publicly apologise in a way which would publicly humiliate themselves just before the home GP, have one or both drivers apologise to the fans? Promise never again to use team orders?
Somehow none of that sounds like Ferrari, I don't want to see the fight kicked out of Ferrari but they need to find a way to ensure they fight fair
