Going to disagree wtih this.
The USA-NKF is the governing body for the USOC, when it comes to Karate, and using their rules, you'll see punches and strikes to the head. Given that the WKF follows virtually identical rules, I see no reason why such a ruleset couldn't be applied to the Olympic Games as well.
USA-NKF is member of WKF, as national organizatory body.
While they do have a specific USA-NKF ruleset, this is just the local adaption of the standard WKF rules.
The kobudo rules are a local invention tough. They are not part of WKF.
All-out face contact, of course, isn't allowed, but they do allow a fair amount of contact to the face area, and people do get popped by backfists / ridge hands on the side of the head as well (anywhere there is non-facial hair).
WKF allow hand strikes to the face/head with closed fists, but not open hand techniques. They are strictly banned.
Contact is skintouch. Although skintouch can be quite hard, the general idea is if you injure the opponent or knock him out/down, you get warned or disqualified.
Under the "new" (now 10+years old) WKF rules, kicks are scored higher points (higher for headkicks) than punches. So kicks, especially high kicks are seen more than punches nowdays. A sad development, made for audience appeal. But face punches ARE allowed.
If they included empty hand kata as well as kobudo competition, in addition to the usual kumite, why not? After all, gymnastics and swimming have multiple events in which the athletes can compete.
No.
The rules that are under considerations are WKF kumite and MAYBE kata (I have to check, but I dont think so) rules. Administrated by WKF as international organizatory body. No kobudo, no kumite rules variations. Nothing. Strict WKF as it is done today. Nothing else.
If some other karate sport (lets say knockdown karate rules for example) should want acceptance by IOC, it must first be accepted and administrated by the WKF as it is now the international karate organization recognized by IOC.. and unlike wrestling, WKF has no interest in housing several types of rules sets under its roof.
