The 2016 contracts don't count too much.
It's just an agreement with the promoter but it is not confirmed officialy by the FIA. So Sardinia is in danger as well as other rounds like Portugal and France.

I fear it will be Corsica to leave and we will have one less tarmac rally which is a real shame. I hope they will do something about it.

If one has to leave that should be Mexico in my opinion.
