Interesting that there is no reference to how many classes will eventually race. E.g. will there still be a female _and_ male keelboat?

Not much hope for another multihull class, IOC wants sailing to decrease the number of athletes due to economic reasons.

F-18 class dont want olympic status (yet at least), so they probably never applied. Good move in my opinion.
Hobie Tiger could be OK as a one design boat in the olympics, but the Tornado is a more versatile class as you can adapt sails and fittings to creweight and personal sailing style.

Politics is probably a _very_ large part of it. There has been roumors that the Finn (male singlehander event) might be dropped so Rogge, a former Finn sailor, can earn political credit. When the Tornado with double trapze and spi was choosen for 2004, there was a large amount of politics going on.
