I think this is a very important point in regard of youth sailors. The Tiger has its difficulties in F18 class races already and will have even more by 2016. Why should somebody buy a Tiger when one can race in one-class regattas only - do you have any Tornado-regattas in your area? I could participate almost every weekend in a F18-regatta in a distance of max 2-3 hours drive.
I see two options: either a then competetive F18 is chosen for the olympic games - or the Hobie 16. This is the typical youth-catamaran, there are 1000s in race condition around, the class will be still strong in 2016, aso.

I see the advantages of having such a large company like Hobie supporting olympic activities (and probably nobody else would has the resources to do that) - and their interest to still get some money out of their investment in the Tiger. However, I could imagine that they would be willing to support the Wildcat or H16 for Olympia 2016 as well.
