Уже читала по первой выложенной ссылке. Насколько я поняла текст, их не допустят точно:
"...
To ensure a fair competition at the 2013 kiteracing world championships and beyond, the IKA Technical Committee has therefore recommended to delete the grandfathering rule with immediate effect.

The next edition of the class rules, to be voted on during the next AGM, also has the grandfathering rule deleted. This proposal had been made already before the recent European Championships in Gizzeria.

The IKA Executive Committee will enforce the deletion of class rule B.1.2 for the 2013 World Championships. Only registered series production equipment currently listed on the relevant equipment lists is eligible to race. A corresponding note under Racing Rule 87 will be posted on the Official Notice Board and included in the Notice of Race.

Т. е. IKA EC поменяла правила класса, не дожидаясь очередного AGM.

Я-то спрашивала насчет "запрета парафойлов" вообще. Что такое Дж и ФС-3?
