That Jun Sai blah blah blah stuff is just fanon. You can probably blame one of them RPG peeps for trying to pass them off as official. They're not on Wookieepedia for a reason.
Kai-kan isn't a form, it's just a re-enactment. Kind of like a more ritualistic version of two-man katas.
Adi Gallia's Shien isn't the same as Form V. Trakata's just a saber technique that makes you look really badass (i.e. Kenobi in Episode II literally disarming Zam Wessell, Corran Horn vs Shedao Shai during the Vong War). Anyway, this doesn't have any bearing on the v1.3 roadmap. Can we move on now, por favor?
