well, mr. President says thay have 7 different options, but imho it should be down to 2 (maybe 3): Full Contact and Point Fighting are the only disciplines that would deserve a bit of attention and could be really entertaining for the combat sports fans.
K1 would be the 3rd (actually, the main, as it's their most famous discipline), but this would make it just "another Boxing", with the Olympics not featuring the best Pro's (for many reasons, from money to the technical aspects of a 15-day tournament).
and as someone already wrote here, it's losing its appeal quickly and deeply, thanks to the raise of MMA (which shouldn't be included in the Olympic schedule for many reasons)
the rest is...well, better to leave it where it is
I have to disagree on a couple of points.
fans? many, especially in certain parts of the World (from USA to Brazil, from South-East Asia -the core of any combat sport- to Eastern Europe, from a few Western European Countries (Italy, and Germany -at least their foreign communities- above all)
something exciting? yes, for the combat sports fans those disciplines are exciting (and point fighting could be also for newcomers, more than the other disciplines under WAKO management...not only, there might be less "manipulation" than in the other events)
adding extra quota places? apart from the fact that the number of athletes at the Games should be increased already with the sports now in charge, if Kickboxing would eventually replace the incorrigible farce named Boxing, some quotas could even be saved (5 men, 5 women weight classes, 16 fighters per event = 160 total athletes, way less than the current boxers)
not saying that I want Kickboxing in the Olympic program (actually, I'd like more the return of Karate, Kumite only of course...and many more martial arts could be interesting, even if they're not so well spread at the top of the sport part like Kickboxing), just to point out that it's pretty much possible to replace the incorrigible cheaters with another combat sport...and without making it difficult to the organizers.
