"The number of sailing events in the olympic games tend to be reduced due to pressure from the IOC. Additions are unlikely" -- Luiz
Exactly right, Luiz, which is why all we can work toward is replacement of existing classes with multihulls.
Also, are you saying that Paul Henderson is a Finn sailor? He is going to be out as ISAF President this fall. And he has already said that he is going to be sailing a multihull after his departure as President. So that might help.
As far as Ben Ainslie winning the gold medal for Great Britain in the Finn Class, who knows what he is going to be doing four years from now. He tends to sail a lot of different boats, and he will probably be much in demand for big-paying jobs on big boats. I doubt if he has any strong loyalty to the Finn Class.
