Actually there hasn't been any official announcement about the rally being held...

ACI's president was mad against the region institution because of money... (region has always paid 1million, and ACI started asking 1,5 because they need 4 to organize everything).
ACI's president some month ago, after being refused to get 1,5 millions, clearly said at press that the event would never be run in Sardinia again. That he would have find an agreement with 2-3 other regions in the mainland.
Nothing of this has happened so the rally should be held in Sardinia again 90%, but actually no official announcement has been released.

I've bought the flight by the way (because it was only 20€, a nice offer), I think they will do it at the end.

Anyway ACI has less money also because it has paid a lot to keep Monza GP in F1. Damn F1.
